Initial Resources At La Joya Property
VANCOUVER, BC - SilverCrest Mines Inc. has completed its initial resource estimation for its La Joya Property in Durango, Mexico. Inferred Resources within the Phase I area are estimated at 57.9 million tonnes grading 28 gpt silver, 0.18 gpt gold, and 0.21% Cu. Initial resources contain approximately 51.3 million ounces of silver, 333,400 ounces of gold (16.7 million ounce of Ag Eq.) and 270.3 million pounds of copper (33.9 million ounces Ag Eq.) for a total of 101.9 million ounces silver equivalent (Ag Eq) using a cutoff grade of 15 gpt Ag Eq.
These resources have been independently estimated utilizing Company Phase I drilling and sampling programs along with independently-validated historic data. Drilling to date has been relatively widespread in the Phase I area which is approximately 1 kilometre by 500 metres. As a result, the initial resource estimates are considered by the Company to cover only a portion of the overall potential within the Phase I area.
The Main Mineralized Trend which includes the Phase I and II drilling areas has an overall length of 2.5 kilometres and an average minimum width of 500 metres. Phase II drilling is currently underway.
Using a higher cutoff grade of 30 gpt Ag Eq. reduces the Inferred Resource tonnage to an estimate of 35.5 million tonnes with increased grades of 39 gpt silver, 0.22 gpt gold, and 0.30% Cu. Compared to the lower cutoff grade of 15 gpt Ag Eq., these resources contain approximately 44.3 million ounces of silver, 246,000 ounces of gold and 237.5 million pounds of copper or a total of 86.4 million ounces silver equivalent(i).
The resource estimation for La Joya is based on recent and historical information collected by the Company and previous operators (Luismin/Goldcorp) from1979 to present. The most significant components of the data for the Phase I resource area are the recent results from 27 drill holes (5,753.7 metres) and 178 surface samples (504.7 metres) completed by the Company. Eight previously announced independently validated historic drill holes (2,574.35 metres) were also used for resource estimation. Drill hole spacing for the 35 holes (8,328 metres) used in the resource estimation is approximately 100 metres. The entire database includes 83 drill holes totaling 21,473 metres, 77 holes on the Company concessions and 6 holes on the adjacent Goldcorp concessions. There are 48 holes located outside of the Phase I resource area that are being used to guide Phase II drilling.
Selective areas of lead, zinc, tungsten and molybdenum mineralization are also being evaluated. These metals are considered potential by-products of the Ag-Au-Cu mineralization. Resource estimations for these metals will be reported when completed and incorporated in the Technical Report.
Based on available data and computer modeling, the current most continuous mineralization at La Joya is hosted within at least 9 sub-vertical, near east-west striking structurally-controlled stockwork zones. These zones are considered to be semi-continuous along strike with true widths ranging from 15 to 50 metres using a cutoff grade of 15 gpt Ag Eq. At least 14 near-horizontal mantos (semi-continuous disseminated stratabound sulphides) have been defined within the resource area, which are cross-cut by the stockwork zones and are currently considered secondary to stockwork mineralization. The La Joya deposit is currently interpreted to host four related styles of mineralization.
