Yale Resource: Drilling confirms 1.3 kg /tonne Silver

Yale’s drill results from their Zacatecas, Mexico property confirmed the presence of bonanza grades of silver across narrow veins. The best intercept was 1340 grams per tonne over .8 metres. This concludes Yale’s phase 1 drill program. Upon completion of drilling of the San Sabino phase 1 drill program, Yale will have earned its 65% interest from joint venture partner Impact Silver Corp. (TSX.V:IPT)

Mina San Jose:
Four holes totalling 501.25 metres were drilled to test approximately 230 metres of strike length of the vein zone. The holes successfully tested the system at a vertical depth of 60 to 75 metres. Mineralization appears to be associated with a 2 to 4 metre wide structural zone that hosts disseminated and stringer pyrite with associated patchy base metal sulphides and possible sulphosalts.

The first hole was designed to test the vein approximately 50 metres from historical workings that returned over one kilogram per tonne silver from dump samples. This hole returned a significant intercept of 1,340 grams per tonne of silver at a vertical depth of approximately 75 metres below surface.

Salvador/Zacatecas:
Twelve holes totalling 1,314.5 metres were drilled on the contiguous Salvador and Zacatecas properties. The holes tested approximately 300 metres of strike length of the Salvador Vein and 200 metres of strike length of the parallel Zacatecas Veins.

Mineralization within the Salvador Vein was tested with seven holes. Of the seven holes drilled within the Salvador property, two (SZ-02 and SZ-06) were lost due to poor ground conditions; in each case the replacement hole for the two lost holes was drilled to intersect the vein at a greater depth. It appears that the veins are at a higher elevation in the mineralizing system than previously understood. Local faulting was seen in several holes and this may have an effect on the mineralization. The deeper mineralization has a much higher base metal content.The Salvador Vein is a quartz-calcite vein with associated pyrite, sphalerite and galena and has several metres of stringer zone in the footwall. The vein is part of a broad structural zone that continues to depth and drilling tested this zone to depths of up to 110 metres.

Five holes were drilled to test the Zacatecas property. Drilling has shown that at least three veins are better developed at the extreme north of the property and appear to continue toward the south. Local narrow sulphide-rich veins intersected resulted in high-grade intervals such as in SZ-09, which intersected 416.0 g/t silver and 2.1 per cent zinc over a core length of 25 centimetres. The main vein target was successfully intersected along with previously unknown stringer zones. The main vein appears to be a vein set – on one section holes were drilled in two directions to better understand the vein geometry. Mineralization within the Zacatecas veins is more coherent than the Salvador Vein and has more visible sulphides.

The Salvador Property is located approximately 5 km southeast of the Veta Grande processing plant. Vein outcroppings and old workings indicate that the primary vein within the Salvador property can be traced for greater than 1 km. The central 400m of the open pits trace a very well defined 2-5m wide structure and a secondary vein nearby. There are three main shafts along the length of the vein: one at a presumed vein intersection and another outside the principal vein area, presumably for the ore extraction, access and services. There are at least two known splays to the principle vein. Along the length of the vein there are old mine dumps of various sizes.

Testing will now focus on the tailings dumps, which have previously sampled 200 – 300 grams per tonne of silver. Yale and Impact estimate there are "many thousands" of tonnes of tailings, which will be processed at Impact’s 200 ton per day mill located in the Veta Grande area of Zacatecas that is currently operating on a toll mill basis. Presently IMPACT holds 25% Net Profit Interest in the mill, with an option to purchase 100% interest.

Historic mines throughout the San José property and samples near these mines grading up to 145 ounces per tonne silver combined with the recent results from outcrops, show that there is significant exploration potential. The Zacatecas district is one of the most famous historic silver mining districts in Mexico.

A significant aspect to the potential at San José is the consistently elevated gold values. Previous sampling of dumps identified gold values up to 7.0 g/t. Recent sampling returned 2,180 g/t silver (or 63.5 ounces per ton) and 3.15 g/t gold.
