This resource represents only the upper, close to surface portion of three structures; the El Creston structure over approximately 670 m of strike length; the Cinco de Mayo - Santiago structure known to be at least 3 km long and drill tested over approximately 2.5 km of strike length; and the El Rey structure tested over approximately 250 meters of strike length.
Highlights
- 383,000 oz ounces gold equivalent (calculated using only Gold oz + Silver oz/60, assumes 100% Au & Ag recoveries (excludes base metal content))
- 276,000 ounces of gold
- 6.429 million ounces of silver
- 33.483 million pounds of copper
- 110.457 million pounds of lead

NOTES: 1. The cutoff for oxidized resources is higher than un-oxidized
resources due to anticipated lower metal recoveries in the
flotation process.
2. Gold-equivalent grades are used for cutoff purposes only.
3. Gold equivalent calculation: g Au-equiv/t equals Au grade + (Ag
grade ÷ 60) + (Cu grade ÷ 0.35) + (Pb grade ÷ 1.0938) +
(Zn ÷ 0.875).
Historic metallurgical testing preformed between 1986 and 1991 by The Comision de Fomento Minero, a Mexican governmental organization, on a 150 kg. sample of un-oxidized material from the El Creston area gave flotation recoveries of:
---------------------------------------------------------------------
Element Recovery to Lead Concentrate Recovery to Zinc Concentrate
---------------------------------------------------------------------
Au 81.1% 4.2%
Ag 87.6% 6.7%
Pb 97.2%
Zn 86.1%
---------------------------------------------------------------------
Copper recovery was not determined by this historic metallurgical test.
Ongoing Exploration
Since the initial data for this resource calculation was submitted to MDA, the Company has completed the drilling of 41 additional holes. The core samples from these holes have all been delivered to the lab and are at varying stages of analysis. The results from these holes will be reported as they are delivered to the Company. Drill results gained during this year's exploration program will be subsequently modeled and included in the Company's next updated resource calculation likely to be initiated in late 2008. Please refer to the Company's web site to view a surface drill plan identifying the structures and drill hole locations used in the resource calculation at http://www.sohoresources.ca/res.cal....
"We are very pleased to deliver to our shareholders our first NI 43-101 compliant resources," states Mr. Ralph Shearing, President and CEO of the Company. "This is a solid and strong initial resource for a junior company, calculated by a conservative, highly reputable and experienced engineering firm. With the ongoing exploration program running smoothly and efficiently full speed ahead, we are confident that Soho will substantially add to and increase this initial resource by drilling along strike and down dip on the three structures from where our initial resource has been calculated. We also have many other structures hosted within the district scale mineralizing system and contained within our project concessions that have not yet been drill tested. We hope that drill testing these structures in the future ongoing exploration program will also contribute resources to the project resource inventory."
The Tahuehueto mineral resources were modeled and estimated by: (1) evaluating the drill data statistically; (2) interpreting mineral domains for each element independently on vertical cross sections spaced at intervals of 25 or 50 meters across the strike length of the mineralization; (3) coding the block model by projecting the mineral domain interpretations horizontally half the distance to adjacent sections; (4) analyzing the modeled mineralization statistically to establish estimation parameters; (5) capping high grade domain assays at Au cap equals 60 g Au/t , Ag cap equals 370 g Ag/t, Cu cap equals no cap, Pb cap equals no cap, Zn cap equals 20%; and (6) estimating metal grades into the coded three-dimensional block model by inverse-distance methods using approximately 4,700 sample intervals with 2 meter composites from a total of 165 drill holes (129 core and 36 reverse circulation holes). All modeling of the Tahuehueto resources was performed using Surpac(R) software.

Soho Resources Corp. is a Canadian junior mining and exploration company with a strategic focus on gold, precious and base metals. The company's current focus is directed towards the exploration and development of the "Tahuehueto Project", located in the northwest corner of Durango State, Mexico, within the prolific Sierra Madre mountain range. The Tahuehueto Project is typical of a classic Mexican epithermal vein system that hosts multiple large scale structures strongly mineralized in Au, Ag, Pb, Zn, and Cu.
