73.1 MILLION OUNCES SILVER EQUIVALENT RESOURCE IN DURANGO STATE, MEXICO

Business Summary

Orko Silver Corp. focuses on resource exploration and development for Silver and Gold in Mexico.

The Company has a large land position in Durango State, a historically prolific silver mining region located along the Sierra Madre Occidental Mountains and is involved in three main projects, La Preciosa, Santa Monica and San Juan. The company owns a 100% interest in La Preciosa Project and is earning a 75% interest in the adjacent Santa Monica Project from Goldcorp, Inc. (NYSE: GG) by expending $US 1.5 Million on exploration. As well, the Company has an option agreement to earn a 75% interest in the adjacent San Juan property from Silver Standard Resources Inc. (NASDAQ: SSRI) by expending $750,000 on exploration.

La Preciosa Project - Orko Silver controls 100% of its La Preciosa project.

On March 27, 2007 Orko introduced one of its largest veins "Martha", which is an intercept of the Abundancia Vein in "La Preciosa Norte" sector.

It yielded 6.45 metres true width grading 640.6 g/t Ag and 1.101 g/t Au, for a Silver-Equivalent of 706.7 g/t including 3.92 metres true width grading 981.3 g/t Ag and 1.585g/t Au for a Silver-Equivalent of 1,076.4 g/t in hole BP06-78.

On May 09, 2007 "Martha" impressed again, yielding 13.79 metres true width grading 376.5 g/t Ag and 0.320 g/t Au for a silver-equivalent of 395.7 g/t, including 3.07 metres true width grading 1,374.0 g/t Ag and 0.605 g/t Au for a silver-equivalent of 1,410.3 g/t.

On March 13th, 2007, the company released its third NI 43-101 compliant Inferred Resource Estimate of 4.39 million tonnes grading 229.9 silver grams per tonne (g/t) and 0.396 gold g/t, for a silver-equivalent grade of 253.7 g/t. This represents a contained silver-equivalent metal content to 1,114 million grams, 35.8 Million Ounces. This resource estimate is for the Abundancia and La Gloria Veins each over a strike length of 1.2 kilometres, Luz Elena Vein for 800 metres and Esperancita Vein for 300 metres in the "Mina La Preciosa Sector", plus the Abundancia Vein for a further 850 metres in the "Zona Sur Sector". This resource estimate is up to and including hole 76.

On September 7th, 2006, the Company released its second NI 43-101 compliant Inferred Resource Estimate of 3.43 million tonnes grading 0.435 g/t Au and 235.0 g/t Ag for a Silver-Equivalent grade of 261.1 g/t. (8.35 oz/ton). The contained metal equals 25.8 million ounces of Silver and 47,800 ounces of Gold for a Silver Equivalent to 28.7 Million Ounces. The data obtained from an additional 14 drill holes on the two main veins, La Gloria and Abundancia, increased this resource estimate by 30%. The first NI 43-101 compliant Inferred Resource estimate was released on January 19th, 2006. Data from 26 drill holes totaling 11,579 metres form the basis of an Inferred Resource of 2.72 million tonnes grading silver 227.2 g/t and gold 0.464 g/t, for a silver-equivalent grade of 255 g/t. Contained metal in the Inferred Resource equals 618 million grams silver (19.9 million ounces silver) and 1.26 million grams gold (40,400 ounces gold) for a silver-equivalent content of 694 million grams, 22.3 Million Ounces Silver Equivalent.

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 5 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.

Less than 30% of the initial target has been drilled and only to a true depth of 340 metres. The deposit remains open in all directions and to depth. The Company is drilling 24 hours a day, 7 days a week at La Preciosa utilizing 2 diamond drill rigs.

Santa Monica Project

Santa Monica is adjacent to the La Preciosa project optioned by Orko from GoldCorp Inc. The Santa Monica Property covers over 17,285 hectares and is located approximately one hour and a half away by paved road from the City of Durango, in Durango State, Mexico. Currently, Geophysical Surveys are underway which began on March 18, 2007.

Objective

To Locate a vein system like San Sebastian Mine (Hecla Au-Ag mine)

Strategy

• First Step: Regional floating quartz sampling survey (Completed)
• Second Step: Local grid each 25 meters sampling trenches (bulldozer)
• Third Step: Diamond drill program of initial target areas

Available Data: Geophysical survey (I.P.); Vapour Mercury survey

An exploration program is expected to commence in the near future.

San Sebastian Mine: Discovery Method

• Regional floting quartz sampling survey
• Local grid each 25 meters sampling trenches
• Diamond drill program of initial target areas (70 ddh)
• Annual Production: 80,000 oz Au Eq.
  Cut-off: 4 gr.
  Recovery: Ag 90%, Au 96%
  Average Grade: 17 gr Au Eq.
  Staff: 150 people (included 12 geologists)

The San Juan property

is 24,580 hectares and is located North-West from La Preciosa Project. The company has an option agreement with Silver Standard Resources Inc. (NASDAQ: SSRI) to earn a 75% interest, by expending US$750,000 on exploration. Thus far, three silver-gold epithermal veins have been located; La Plomosa, El Vacaro and San Juan veins are known to outcrop on this property.

Objective

To locate a similar vein system like Abundancia on La Preciosa Project.

Strategy

• First Step: Regional floting quartz sampling survey (Currently underway)
• Second Step: Local grid each 25 meters sampling trenches
• Third Step: Diamond drill program of initial target areas

Recent News: Orko Silver Expands the Martha Vein to the Southeast at La Preciosa

Orko Silver Corp. announced that it has received further assay results from the current diamond drilling program on La Preciosa Project in Durango, Mexico.

Additional drilling has extended the Martha Vein southeastward; including a thick mineralized zone 400 metres south of the area reported in the October 1st, 2007, 43-101 Compliant Resource Estimate.

Hole BP07-146 hit a true width of 15.15 metres grading gold 0.321 g/t, silver 141.7 g/t for a silver-equivalent of 160.9 g/t. It includes a higher grade core of 8.20 metres grading gold 0.519 g/t, silver 213.3 g/t for a silver-equivalent of 244.5 g/t. This hole expands the area previously reported with hole BP07-135, which yielded 16.55 metres of gold 0.363 g/t and silver 355.9 g/t for a silver equivalent of 377.7 g/t (see news release dated November 19th, 2007).

Gary Cope, President of Orko Silver, adds, "These results continue to demonstrate that the Martha Vein is a major developing story at La Preciosa.

The grades combined with large widths are very encouraging for our next 43-101 Resource Estimate expected to be released at the end of the first quarter.

We are also happy to report that the 2008 Exploration program is now fully operational with all 4 rigs drilling at La Preciosa."

Fundamental Considerations

• Drilling underway using 4 rigs working 7 days a week, 24 hours a day. Over 73,000 metres of drilling has been completed to date at La Preciosa

• Assay results will be forthcoming from the tremendous amount of drilling done and continues at La Preciosa. The current resource estimate includes results up to and including hole 120. In the next one, expected in March 2008, 40 more holes will be added.

• Orko has further tested the Martha vein and drilled hole 202 which have analyses pending.

• Less than 30% of the targets have been drilled and only to a true depth of 400 metres. The deposit, consisting of multiple veins, remains open along strike and at depth.

• Current mineral resources are contained dominantly in four of the multiple veins intercepted to date.

October 2007

Completed 4th NI 43-101 Inferred Resource Estimate:

• 10.36 million tonnes grading 0.328 g/t Au and 200.0 g/t Ag at a cut-off grade of 100 g/t for a Silver-Equivalent grade of 219.0 g/t

• 73.1 Million Silver Equivalent Ounces (Oct 1st, 2007) and was based on hole 120.

• NEW NI 43.101 INFERRED RESOURCE ESTIMATE EXPECTED TO BE RELEASED WITHIN WEEKS AND WILL INCLUDE HOLE 160 - IT COULD POSSILBY APPROACH OR EVEN EXCEED 100 MILLION OUNCES AND MORE LATER ON WHEN ANOTHER 60 HOLES WILL BE ADDED.

• Coeur d'Alene Mines (NYSE:CDE) has recently completed the purchase of Palmarejo for US$1.1 billion and paid $ 4.68 per Ounce of Silver (Ag-Eq oz)

• Orko will have a MC/Oz of Silver Eq, as per our estimate, of $ 1.60.

• When CDE purchased Palmarejo, the silver price was at $ 13, 35% less than today.

NEXT 43-101 EXPECTED IN MARCH 2008: WILL INCLUDE 40 MORE DRILL HOLES

(They work hard in Mexico!)
