Sterling Mining Company Announces Trenching Results at San Acacio
|
| | WALLACE, IDAHO - December 4, 2006 - (BUSINESS WIRE) - Sterling Mining Company (OTC: SRLM, FSE:SMX) announced today that it has completed a program of surface trenching along 900 meters of the Veta Grande at the San Acacio Mine, in Zacatecas, Mexico. The Veta Grande can be traced for almost seven kilometers and is known to host silver mineral to a depth of at least 300 meters. The upper portions of the vein are oxidized and are amenable to treatment at Sterling's nearby Barones vat leach plant.
The weighted average of all samples in the 41 trenches is 149 gpt Ag (a total of 93 samples were collected). The average width of the vein is 12.33 meters. The trenches were placed across the vein at an average spacing of about 25 meters.
- 41 Trenches sampled over a strike length of 900 meters
- Best four trenches returned:
- 377 gpt Ag over 10.85 meters,
- 376 gpt Ag over 13.93 meters,
- 386 gpt Ag over 22 meters and
- 472 gpt Ag over 5.15 meters
- The vein and backfill sampled in the trenches average 149 Ag gpt over 12.33 meters.
Sterling personnel, using a backhoe to dig to depths of up to three meters, conducted the sampling program. Samples were taken both along the bottom of the trenches and along the sides, in order to ensure a representative sample free of surface contamination. The goal of this program was to verify previous surface sampling and to investigate the near-surface material as a source of feed for Sterling's nearby Barones mill.
All assay samples were transported directly to the BSI Inspectorate laboratory in Durango. The samples were analyzed using fire assay with a gravimetric finish. Samples were also analyzed for copper, zinc and lead values for metallurgical use only. Base metals are not recovered in the Barones mill circuit and therefore they have no economic value.
Sterling personnel are evaluating the results to determine preferred areas on the surface that can be safely mined and economically processed for silver.
Previous underground workings provide access in three dimensions to the mineralized system. The Refugio tunnel is currently being rehabilitated to provide access for bulk sampling of stopes that were mined by hand during the Spanish colonial period. Previous mining in these stopes was by hand, with higher grade material extracted and the remaining material left behind. Sterling personnel collected a number of samples in the accessible part of the Refugio adit in order to verify previous sampling programs and to investigate the potential for mill feed. The results of that work are not yet available.
