Pan American Silver and Orko Silver Announce Positive Test Results at the La Preciosa Project

Metallurgical Testing Yields 91% Average Silver Recovery

VANCOUVER, BRITISH COLUMBIA--(Marketwire – Dec. 16, 2009) - Orko Silver Corp. ("Orko") (TSX VENTURE:OK) and Pan American Silver Corp. ("Pan American") (TSX:PAA)(NASDAQ:PAAS) are pleased to announce that phase one metallurgical testing conducted on representative samples of the different veins at the La Preciosa joint venture project in Durango, Mexico have yielded excellent results.

Pan American has completed a first phase detailed metallurgical program, which included: work index tests, abrasion tests, mineralogical studies, gravity tests, floatation tests and cyanide leach tests. The program was a follow-up to the preliminary testing conducted in 2008 by Orko (Orko's news release April 17, 2008). Additional flotation studies are still underway.

Simple cyanide leaching yielded average silver recoveries of 91%, although the use of selective oxidants could further enhance these results. In addition, Pan American has been successful in reducing cyanide consumption to 1.6 kg/t, which is materially lower than the results from the metallurgical work previously completed by Orko. Lastly, the current test work has shown that with the use of oxidants, the leach cycle times can be reduced to 48 hours with minimal impact on ultimate silver recovery.

Gary Cope, president of Orko Silver Corp., stated:

This is excellent news. Confirming the straightforward leaching characteristics of the ore while reducing both cyanide consumption and leach times are clear enhancements to the La Preciosa project.

Also commenting on the metallurgical results, Geoff Burns, President and CEO of Pan American Silver, said:

These are very good results and better than we expected. We are fully engaged in all aspects of the project and still expect to produce a full feasibility study for La Preciosa by the end of next year.

In addition to continuing delineation and exploration drilling, as well as doing additional metallurgical testing, the project is being actively advanced on a number of other critical path items. Hydrogeological services have been contracted to begin determining appropriate water sources and Pan American has been in active dialogues with the local communities and land owners in the project's immediate vicinity who would be affected by La Preciosa's development.

Pan American Silver And Orko Silver Begin Comprehensive Drilling And Development Program At 'La Preciosa'

By 79Atoms on Tuesday, August 18, 2009

June 22, 2009.
Pan American Silver And Orko Silver Begin Comprehensive Drilling And Development Program At "La Preciosa".

(Read original article here.)

Vancouver, British Columbia - June 22, 2009 - Pan American Silver Corp. ("Pan American") (PAAS: NASDAQ; PAA: TSX) and Orko Silver Corp. ("Orko") (OK: TSX.V) are pleased to announce that this week they commenced a comprehensive exploration and delineation drilling program at the La Preciosa silver project in Mexico.

The Companies expect to complete approximately 30,000 meters of drilling on the property between now and the end of December of this year. The initial delineation drilling is specifically designed to upgrade Martha Vein inferred resources to measured and indicated status, while the exploration drilling will focus on several untested prominent vein structures within the joint venture property, that had been previously discovered by Orko.

Pan American, operator of the La Preciosa joint venture, plans to spend a total of US $5.7 million in 2009, to complete the drill programs, as well as to initiate other project development related activities, including advanced metallurgical testing.

Drilling activities will be carried out by Major Drilling S.A. de CV of Hermosillo. The first rig is now drilling and a second rig is scheduled to commence drilling in the next 10 days. Assay testing will be performed by SGS Mineral Services in Durango, Mexico.

Gary Cope, President and CEO of Orko said, "We are extremely pleased to resume drilling at La Preciosa. Pan American and Orko have jointly developed a program to further delineate the Martha vein while testing for down dip and along strike extensions. But, perhaps more exciting is that we also will begin drill testing several other vein targets that we know exist on the property and we look forward to regularly disclosing drill results, over the balance of the year."

Geoff Burns, President and CEO of Pan American added, "We have assembled a project development team and put together an aggressive drilling program for La Preciosa for 2009. We are set up, we are in the field working and I am extremely optimistic about the potential for a meaningful expansion of the resource base."

On April 14th, 2009 Pan American and Orko jointly announced an agreement to create a joint venture to develop the La Preciosa silver project in Mexico. The La Preciosa and adjacent mineral concessions of Santa Monica and San Juan cover 32,422 hectares of contiguous mining claims. Orko had previously defined an indicated resource estimated at 10,637,000 tonnes grading 185 grams of silver per tonne and 0.27 grams of gold per tonne for a total of approximately 63,000,000 ounces of silver and 94,000 ounces of gold. In addition, the property hosts an inferred resource estimated to comprise 12,087,000 tonnes, grading 185 grams of silver per tonne and 0.25 grams of gold per tonne, for a total of approximately 71,700,000 ounces of silver and 97,000 ounces of gold.

The Joint Venture partners have agreed to delay the completion of a Preliminary Economic Assessment until the 2009 drilling and metallurgical test program has been completed. This will allow them to accumulate more extensive resource and metallurgical detailed data that will form the basis of the comprehensive Preliminary Economic Assessment.

George Cavey, P.Geo., Orko's Vice-President, Exploration, is the Qualified Person who takes responsibility for the technical disclosure in this news release.

Pan American Silver And Orko Silver To Jointly Develop The 'La Preciosa' Silver Project

By 79Atoms on Tuesday, April 14, 2009

April 14, 2009
Pan American Silver And Orko Silver To Jointly Develop The 'La Preciosa' Silver Project

(Read original article here.)

Vancouver, British Columbia - April 14, 2009 - Pan American Silver Corp. ("Pan American") (PAAS: NASDAQ; PAA: TSX) and Orko Silver Corp. ("Orko") (OK; TSX.V) are pleased to announce that they have reached an agreement for the joint development of Orko Silver's La Preciosa silver project in the state of Durango, Mexico.

The Project

The La Preciosa silver project and adjacent mineral concessions of Santa Monica and San Juan, cover 32,422 hectares of contiguous mining claims on which Orko has already defined an indicated and inferred mineral resource. The indicated resource is estimated to comprise 10,637,000 tonnes, grading 185 grams of silver per tonne and 0.27 grams of gold per tonne, for a total of approximately 63,000,000 ounces of silver and 94,000 ounces of gold, while the inferred resource is estimated to comprise 12,087,000 tonnes, grading 185 grams of silver per tonne and 0.25 grams of gold per tonne, for a total of approximately 71,700,000 ounces of silver and 97,000 ounces of gold. The primary discovery is the Martha vein, which ranges from 2 to 40 meters in thickness and has been traced over 3.5 kilometers on strike. Martha remains open at depth and along strike, as do several other promising veins and earlier stage exploration targets within the remainder of the La Preciosa claims. For more details on the resource estimates, refer to the technical report by Mine Development Associates ("MDA") dated March 31, 2009. George Cavey, P.Geo., Orko's Vice-President, Exploration, is the Qualified Person who takes responsibility for the technical disclosure in this news release.

The Joint Venture Agreement

Pan American and Orko have agreed to form a joint venture to develop the La Preciosa project. Pan American will contribute its demonstrated mine development expertise, as well as 100% of the funds necessary to develop and construct an operating mine, in consideration for a 55% interest in the joint venture, while Orko will contribute its exploration expertise and the La Preciosa project and related concessions to retain a 45% interest.
Over the next 36 months, Pan American has agreed to spend an estimated US$16 million at La Preciosa to conduct resource definition drilling, acquire necessary surface rights, obtain permits, and ultimately prepare and deliver a feasibility study to maintain its interest in the Joint Venture. Furthermore, Pan American has agreed to spend a minimum of US$5.0 million in the first 12 months of the development program to maintain its interest in the Joint Venture, of which a minimum of US$2.5 million will be spent to continue to explore the highly prospective land package that Orko is contributing to the Joint Venture.

Key terms of the joint venture and the development strategy for La Preciosa include:

Pan American will be the operator for the joint venture and has agreed to share with Orko all technical information relating to the development of La Preciosa

A joint venture Management Committee will be formed, with representation from both Orko and Pan American, which will be responsible for monitoring the project's development

Any mine construction decision and subsequent operating budgets will require the unanimous approval of the Management Committee

Pan American has agreed to a "standstill" with Orko for as long as the joint venture is in operation.

Commenting on the agreement, Mr. Geoff Burns, President and CEO of Pan American stated: "I am extremely pleased to be partnering with Orko Silver in the joint development of La Preciosa. Orko has done a first class job in defining a very significant silver resource and the project is at an ideal stage to take the next step towards future production. Having just completed the development and construction of two mines, we had been actively seeking opportunities to re-deploy our talented team of mine builders. The timing is right, the location is right and the resource seems right to allow for some real value creation and growth for both Pan American's and Orko's shareholders."

Mr. Gary Cope, President and CEO of Orko commented: "We have long believed in the value of La Preciosa and it is rewarding to know that Pan American has recognized that same potential by committing both its capital and human resources to the project. We believe that with further exploration we should be able to define a significantly larger silver resource. Most importantly, we have structured a Joint Venture which is truly an open partnership. Orko's shareholders will benefit from the financial capacity and extensive mine development expertise that Pan American brings to the joint venture. As such, this transaction significantly reduces the financing and dilution risk for our shareholders. We believe this will be a strategic advantage for Orko and we look forward to working closely with Pan American's team as La Preciosa moves toward production."

GMP Securities L.P. and BMO Capital Markets acted as financial advisers to Orko and have both provided fairness opinions that the transaction is fair from a financial point of view.

Private Placement

Coincident with the formation of the La Preciosa joint venture, Pan American has also agreed to purchase, on a private placement basis, 4,000,000 common shares of Orko at a purchase price of CDN $1.25 per share. Pan American's investment in Orko's common shares is subject to certain anti-dilution and pre-emptive rights to participate in future financings of Orko. The price represents a premium to the current market price and further reflects Pan American's confidence in the value of the project. The private placement is subject to acceptance by the TSX Venture Exchange.

Orko Silver Increases and Upgrades La Preciosa Resource Estimate

By 79Atoms on Wednesday, February 18, 2009

Orko Silver Increases and Upgrades La Preciosa Resource Estimate

(Read original article here.)

VANCOUVER, British Columbia - Orko Silver Corp. (TSX.V - OK) -- is pleased to release the latest resource estimate for our La Preciosa silver deposit located in Durango, Mexico. This independent resource estimate has been completed by Mine Development Associates (MDA) of Reno, Nevada. MDA has stated that the La Preciosa deposit now comprises 47% Indicated Resources and 53% Inferred Resources. The current resource estimate is based on all of Orko's drilling, including the 2008 drilling of an additional 205 holes (79,021m).

Previous resource estimates completed at La Preciosa all contained Inferred Resources only. The last resource estimate, of March 31, 2008, outlined an estimated Inferred Resource of 15.35 million tonnes grading 0.321 g/t Au and 190.0 g/t Ag at a cut-off grade of 100 g/t for a Silver-Equivalent grade of 209.2 g/t. Contained metal in the Inferred Resource equaled 93.7 million oz Silver and 158,000 oz Gold, totaling 103.2 million oz Silver Equivalent*.

Gary Cope, President of Orko, adds: ""It has been very rewarding to have watched La Preciosa grow from a "Grassroots" exploration play, into one of the top new silver discoveries in the world. This resource increase when combined with the upgrade of 47% of the total ounces to the "Indicated" category gives us the confidence that we are well on our way to demonstrating the potential for another large silver mine in Mexico. Our immediate plans include continuing with our delineation of the Martha Vein, including infill drilling and to begin the drill testing of other targets such as Nancy, El Orito Norte and El Vaquero."

In total, eight veins were modeled including the Martha Vein, which dominates the resource. In the process of modeling, lithological units were differentiated which helped in establishing the orientation and continuity of the individual veins. Using geological data along with the metal grades, it was possible to establish continuity of mineralized zones of stockwork, breccia, veins, and veinlets. The high-grade veins within these zones were segregated and modeled. All zones and veins were modeled into a three dimensional solid. Once defined, statistics of each domain and each vein were evaluated separately, and capping was carried-out individually for each vein and domain. The sample data was then composited to three-metre intervals. Grade continuity was evaluated separately for each vein and domain. Inverse distance squared estimation was used. A cut-off grade of 100 g/t was selected by MDA. Classification into Indicated and Inferred was dependent upon the vein continuity, geological continuity and proximity to the closest drill hole, as well as the number of samples and the number of drill holes used in the individual blocks.

All reported resources lie within the modeled veins. The reported resource estimate is undiluted using a 60:1 gold to silver ratio with no metallurgical extractive factors applied. The QA/QC work demonstrates reliability of the analytical data and the auditing of the database has shown it is accurate.

Of particular note are the resources contained within the Martha Vein, as outlined in the following table:

Steve Ristorcelli, R.P.Geo. of MDA is the Qualified Person who takes responsibility for the resource disclosure component in this news release.

A complete table of the current resource estimate is available on our website at the link below:

http://www.orkosilver.com/i/pdf/resourceestimate.pdf

Subsequent to the issuance of the resource estimate, a Preliminary Economic Assessment will also be completed by MDA.

The Company is now in possession of final analytical results from the completion of all 354 drill holes at La Preciosa. The Martha Vein oriented drilling program has extended the mineralization in a SSE direction. The Company's geologists have noted a drop in the silver values to the southeast, where drilling has taken place on the periphery of a small Quaternary basaltic volcano. In this area, the Martha vein is thick and strong and this will be one the areas where future drilling will be carried out.

The following table summarizes the result of the balance of the drill holes drilled in 2008. Of particular note is a high-grade intercept for the Martha Vein in hole BP08-319, located on the eastern side of the mineralized trend. Hole BP08-319 yielded a true thickness of 3.57 metres grading 0.184 g/t gold and 257.8 g/t silver for a silver-equivalent of 268.8 g/t. Also of interest is hole BP08-339A which yielded 7.36 metres grading 1.265 g/t gold and 123.5 g/t silver for a silver-equivalent of 199.3 g/t.

Key Martha Vein intercepts added for this release:

Drill holes along the periphery, or which did not reach thickness and/or grade cut-offs, include BP08-307, -308, - 309, -313, -314, -315, -316, -317, -321, -322A, -323, -327, -328, -329, -330, -332, -333, -334, -335, -336, -337, -338, -340, -341, -342, -344, -345, -346, -347, -349, -350, -351, -352, -353, 354. Some of these holes cut significant thicknesses of the Martha vein, wherein low grades were encountered. While not making the underground cut-off grade, they may be considered for future open-pit potential studies.

The Company remains extremely optimistic about its future prospects at La Preciosa. For 2009, Orko Silver plans to carryout in-fill drilling that will allow the Company to increase the resource confidence of the Martha vein, as well as drill testing along the extensions of the other known vein trends, within the overall extensive property package.

All 2008 holes were started in HQ-size core, with reduction to NQ-size core at approximately 260 metre down hole depth. Drill core is logged by geologists who mark sample locations according to lithological/alteration changes. The individual samples are taken over core lengths always less than or equal to two metres and commonly less than a metre. The core is cut in half with a diamond saw. One-half of the core is stored in the original core boxes in core storage buildings on site. The other half of the cut core sample is placed in sample bags and transported by Orko personnel to the SGS Mineral Services or Inspectorate labs in Durango, Mexico for sample preparation and analysis.

Orko Silver Corp. (TSX Venture Exchange: OK.V, WKN: A0J KUL) fokussiert sich auf die Ressourcenexploration und --entwicklung von Silber und Gold in Mexiko. Das Unternehmen besitzt eine große Landposition im Bundesstaat Durango, einer historisch sehr reichen Silberbergbau-Region entlang der Sierra Madre Occidental Berge. Das Unternehmen hat mit drei Hauptprojekten zu tun: La Preciosa, Santa Monica und San Juan. Orko gehören 100 % der Anteile am La Preciosa Projekt, am angrenzenden Santa Monica Projekt kann man 75 % von Goldcorp (NYSE: GG) durch die Investition von 1,5 Mio. US $ in Exploration erhalten. Das Unternehmen hat weiterhin eine Optionsvereinbarung zum Erwerb von 75 % der Anteile am angrenzenden San Juan Projekt von Silver Standard Resources Inc. (NASDAQ: SSRI), indem man 750.000 $ in die Exploration investiert.

Das Unternehmen hat seine meiste Aufmerksamkeit seinem La Preciosa Projekt gewidmet. Am 31. März 2008 gab Orko seine 5. NI 43-101 konforme Ressourcenschätzung bekannt, die eine abgeleitete Ressource von 15,35 Mio. t mit 0,321 g/t Gold und 190,0 g/t Silber bzw. 209,2 g/t Silberäquivalent auswies. Der Mindestgehalt (cut-off) beträgt 100 g/t. Das enthaltene Metall entspricht 93,7 Mio. oz Silber und 158.000 oz Gold oder 103,2 Millionen Unzen Silberäquivalent*. Die Lagerstätte besteht aus mehreren Adern und bleibt im Verlauf und zur Tiefe hin offen.

* Geschätzt bei einem Silber-Gold-Verhältnis von 60:1, Metall- und Schmelzausbeuten werden mit 100 % angenommen.

Von seinem Erfolg auf La Preciosa ermutigt, bohrt das Unternehmen weiter mit 4 Diamantbohrgeräten 24 h pro Tag und 7 Tage die Woche.

Die 5. Ressourcenschätzung des Unternehmens basierte nur auf 156 von 220 bis dato gebohrten Löchern. Orko wird einen konstanten Fluss an Nachrichten mit Probenergebnissen der schon gebohrten Löcher veröffentlichen sowie auch über das laufende Bohrprogramm, darunter die Folgearbeiten an der entdeckten Martha Ader, berichten. Die Martha Ader hat zur aktuellen Ressourcenschätzung wesentlich beigetragen.

Eine neue Ressourcenschätzung wird für das 3. Quartal 2008 erwartet.

Orko Silver Corp. exploriert auch seine Santa Monica und San Juan Projekte. Beide Projekte liegen angrenzend zu La Preciosa und haben beeindruckende geologische Charakteristika. Es besteht exzellentes Potential, dass sie ähnliche epithermale Systeme wie auf La Preciosa beherbergen.

Summary

Orko Silver controls 100% of its La Preciosa project.
click to download in pdf.

Orko Silver Corp. (under previous name "Orko Gold Corporation") entered into an option agreement in late 2003 with two companies under the direction of Luismin S.A. de C.V., now a part of Goldcorp Inc., to acquire an interest in the La Preciosa silver-gold prospect. A news release, dated 4 March 2006, states that Orko has reached an earn-in position and by agreement has 100% of La Preciosa, with Goldcorp holding an equity interest in Orko.

La Preciosa property is located in Durango State, 47 km northeast of the city of Durango. It consists of a block of mineral exploitation concessions covering 1,134 hectares located southeast of the village of Francisco Javier Mina, northwest of the village of Francisco I. Madero and east of the village of Ricardo Flores Magon. The larger adjacent properties of Santa Monica (17,285 hectares) and San Juan (24,580 hectares) are also under option agreements with Goldcorp and Silver Standard respectively.

La Preciosa property covers Tertiary aged gold and silver bearing epithermal quartz veins, with barite and lesser quantities of base metals, primarily zinc and lead. There are three major vein and vein-breccia systems exposed on a series of hills and ridges, separated by flat floored valleys roughly 800 m wide. The main vein system consists of northward striking and westward dipping veins, plus east striking south dipping cross-cutting veins. The eastern vein-breccia system (Zona Oriente) strikes northwest. Two systems may intersect to the north beneath younger basalt. To the west of these is a third sub-parallel vein system, with north and northwest trending veins, dipping to the west.

La Preciosa veins are composed of poly-phase veins of quartz, often banded, smoky, chalcedonic and amathystine, with a substantial amount of barite laths. Sulphide mineralization is scarce on surface and in the shallow underground workings. Drill core contains disseminated sphalerite, galena, pyrite and acanthite, plus iron and manganese oxides. Wall rocks adjacent to the veins are silicified, particularly between the prominent veins La Gloria and Abundancia. Kaolinite and hematite alteration is common, as well as more distal propylitic chlorite, epidote and pyrite.

The oldest rocks, found only in deeper drill core, consist of Jurassic-Cretaceous graphitic schist, chlorite schist and layers of quartzite. Above the metamorphic units is a thick package of Cretaceous polymictic conglomerate, with lenses of arkosic sandstone. This sedimentary package is topped by Tertiary andesite tuff and andesite agglomerate of the regional Lower Volcanic Sequence. No rhyolites of the Upper Volcanic Sequence are found in the immediate study area, but can be seen on cliffs further to the west. The conglomerates and andesitic rocks are the main host rocks for the veins, but mineralization also extends into the metamorphic rocks. There are a few dioritic dykes in deeper core, but intrusive rocks are generally rare. The youngest unit comes from several Quaternary volcanic vents which erupted basalt flows, filling the lower valleys.

Multiple veins in the main structural zone of La Preciosa ridge have been traced on surface for over 5 kilometres and drilling has revealed that the veins continue to the north beneath the basaltic cover. The veins are also interpreted to extend further south of known exposures. Individual veins have been traced for up to 1.6 km. Of the entire structural zone, the Abundancia and La Gloria veins, plus more recently the Martha vein, have been explored in the greatest detail. The Abundancia and La Gloria veins coalesce at depth, the merged vein is known as the Abundancia vein. There are 2.5 km of underground drifts, following the Abundancia and La Gloria veins, as well as a small portion of the Transversal vein. The original workings are over 100 years old, however, about 60% of the drifts were enlarged and resampled 26 years ago by Luismin. There is a winze that leads down to workings 50 metres below the main 2065 level in Abundancia vein. There are also several raises and small stopes which break through to surface on the Abundancia and La Gloria veins above the 2065 level. At the farthest south exposures, El Orito vein was drifted upon for several hundred metres over a century ago, but has had no modern exploration.

Seven diamond drill holes, totaling 1,319 metres, were drilled by Luismin in a 1981-1982 program. The group of holes were mainly collared west of the Abundancia and La Gloria veins to test a 400 metre strike length of the veins roughly 50 to 75 metres below the 2065 level. The best intercept was from BP-1, which hit a true width of 13.6 metres at 232.0 g/t Ag and 0.10 g/t Au. Hole BP-7 was a longer hole which tested Abundancia and La Gloria veins and also intercepted the sub-parallel Luz Elena vein at greater depth. The 1981-1982 drill program was terminated due to falling metal prices at that time. Core from Luismin's program was split and the remaining half is intact and stored on site.

A single 313 metre hole was drilled by Luismin in the eastern vein-breccia system in 1994. The hole intersected a series of variable silicified zones and veinlet stockwork anomalous in Ag, Au, Pb, Zn and Hg, but did not pass through the complete structure.

In the 1980s, Luismin staff prepared several preliminary resource estimates, which were in-house and do not meet the current NI 43-101 reporting requirements for disclosure of Reserves and Resources. The studies showed a general "Resource" in all categories of approximately 320,000 tonnes in the Abundancia and La Gloria veins grading 238 g/t Ag, 0.70 g/t Au and 0.17 % Pb. The "Proven and Probable Reserves" stood at 30,000 tonnes grading 319 g/t Ag, 1.0 g/t Au, with 0.55 % Pb and Zn combined. These estimates do not follow the requirements for reserves and resources outlined in NI 43-101 as they were estimated prior to the enactment of NI 43-101, however, they have been obtained from sources believed reliable. The resource estimates are considered to be historic, are relevant, but have been replaced by recent estimates utilizing much more drilling data and using current CIM terminology.

In June of 2004, Orko commenced a geological mapping and sampling program on La Preciosa. This was followed by a 40 line-km geophysical survey of Induced Polarization in the northern part of the property in January 2005, performed by SJ Geophysics under Orko's guidance. Orko commenced diamond drilling in March 2005 by Major Drilling International on La Preciosa Ridge, targeting Abundancia and La Gloria, but also extending to Luz Elena vein. The first 24 drill holes were completed by late October 2005 totaling 10,259 metres of diamond drill core.

Favourable results from drilling and interpretation of distinct mineral-shoots within the Abundancia and La Gloria veins gave reason for Orko to make a first resource estimate for the property. Using a cut-off grade of 150 g/t silver-equivalent, Inferred Resource Estimate I totaled 2.72 million tonnes grading 227.2 g/t Ag and 0.462 g/t Au for a silver-equivalent grade of 255.0 g/t. Resource Estimate I was released on 19 January 2006 (Gunning and Whiting, 2006).

Drilling continued and Inferred Resource Estimate II was released on 7 September 2006. This estimate was up to hole BP06-38 for a total of 16,334 metres in La Preciosa Ridge area, including Abundancia, La Gloria and Abundancia Zona Sur veins. Using a cut-off grade of 100 g/t silver-equivalent, Inferred Resource Estimate II totalled 4.05 million tonnes grading 207.4 g/t Ag and 0.384 g/t Au for a silver-equivalent grade of 230.4 g/t. Alternatively, at a 150 g/t cut-off, Inferred Resource Estimate II totalled 3.42 million tonnes grading 235.0 g/t Ag and 0.435 g/t Au for a silver-equivalent grade of 261.1 g/t.

Drilling continued and Inferred Resource Estimate III was released on 13 March 2007. Inferred Resource Estimate III -- At 100 g/t Ag-Eq cut-off the estimate is 5.72 million tonnes grading 192.9 g/t Ag and 0.345 g/t Au, for a silver-equivalent of 213.6 g/t. At 150 g/t Ag-Eq cut-off the estimate is 4.39 million tonnes grading 229.9 g/t Ag and 0.396 g/t Au, for a silver-equivalent of 253.7 g/t.

Drilling continued and Inferred Resource Estimate IV was released on 1 October 2007. Inferred Resource Estimate IV -- At 100 g/t Ag-Eq cut-off the estimate is 10.36 million tonnes grading 199.7 g/t Ag and 0.328 g/t Au, for a silver-equivalent of 219.4 g/t. At 150 g/t Ag-Eq cut-off the estimate is 6.88 million tonnes grading 256.6 g/t Ag and 0.387 g/t Au, for a silver-equivalent of 279.8 g/t.

Drilling continued and Inferred Resource Estimate V was released on 31 March 2008. Inferred Resource Estimate V -- At 100 g/t Ag-Eq cut-off the estimate is 15.35 million tonnes grading 190.0 g/t Ag and 0.321 g/t Au, for a silver-equivalent of 209.2 g/t. At 150 g/t Ag-Eq cut-off the estimate is 6.88 million tonnes grading 256.6 g/t Ag and 0.387 g/t Au, for a silver-equivalent of 279.8 g/t.

The Company's Resource Estimate VI was released Feb 18, 2009 is based the results all the holes drilled to date including the 2008 drilling of an additional 205 holes (79,021m) that was completed after the date of the last resource estimate. The La Preciosa deposit now comprises 47% Indicated Resources and 53% Inferred Resources. Current Indicated Resources are 10.64 million tonnes grading 0.27 g/t Au and 185 g/t Ag for a Silver-Equivalent grade of 201 g/t. at a cut off grade of 100 g/t. The contained metal equals 63.2 million ounces of Silver and 94,000 ounces of Gold for a Silver Equivalent of 68.9 Million Ounces. Current Inferred Resources are 12.0 million tonnes grading 0.25 g/t Au and 185 g/t Ag for a Silver-Equivalent grade of 200 g/t. at a cut off grade of 100 g/t. The contained metal equals 71.8 million ounces of Silver and 97,000 ounces of Gold for a Silver Equivalent of 77.6 Million Ounces.*

In total, eight veins were modeled for the new estimate including the Martha Vein, which dominates the resource. In the process of modeling, lithological units were differentiated which helped in establishing the orientation and continuity of the individual veins. Using geological data along with the metal grades, it was possible to establish continuity of mineralized zones of stockwork, breccia, veins, and veinlets. The high-grade veins within these zones were segregated and modeled. All zones and veins were modeled into a three dimensional solid. Once defined, statistics of each domain and each vein were evaluated separately, and capping was carried-out individually for each vein and domain. The sample data was then composited to three-metre intervals. Grade continuity was evaluated separately for each vein and domain. Inverse distance squared estimation was used. A cut-off grade of 100 g/t was selected by MDA. Classification into Indicated and Inferred was dependent upon the vein continuity, geological continuity and proximity to the closest drill hole, as well as the number of samples and the number of drill holes used in the individual blocks.
All reported resources lie within the modeled veins. The QA/QC work demonstrates reliability of the analytical data and the auditing of the database has shown it is accurate.

* The six resource estimates are all undiluted using a 60:1 gold to silver ratio with no metallurgical extractive factors applied.
Average drill hole spacing is approximately 100 metres for all the holes drilled from 2005-2008. For the 1981-82 program, analytical testing was performed in the Luismin Labs in Durango, Mexico. All 2005-2008 analytical testing has been done by SGS or Inspectorate laboratories, North American based labs both containing ISO certification.

The Martha vein, first identified in hole BP06-77, represents the most significant new target. It is relatively flat lying, dipping an average of 20 degrees to the west. It has a known lateral extent of over four kilometres and varies in widths between 200m to 1.7 kilometres. The Martha vein varies in thickness from one meter to sixty meters and averages about 15. Within that are one or more veins or vein breccias which contain the resource grade material and which average about five meters.

Orko has conducted geological mapping, geophysical testing and has systematically drilled a portion of the known strike length of epithermal silver-gold veins on the property. Two of the veins, La Gloria and Abundancia, were drill tested each along 1.2 km strike length to establish veins on "La Preciosa" which have been traced for five kilometres north-south, as well as multiple east-west veins. Some of the veins include Abundancia, La Gloria, Luz Elena, Carmen, Esperancita, Transversal, Incognita, Nueva, Sur, Ramal Sur, El Orito, Nancy, etc. The Martha Vein has been the focus of drill testing since its discovery in 2007.

The resource estimate results are considered highly favourable by Orko's management. In-fill drilling will be completed by the Company to further increase the confidence in the La Preciosa deposit and to move more of the inferred and Indicated resources into higher resource categories. Expanding Martha vein along strike and at depth, as well as drill testing additional north-south and east-west veins located in the immediate vicinity of the Martha vein, are the main targets.
