It appears to me, unless I am missing something, that the most historic news release I can find on the SLI website, is from Dec 2009. I thought I would post this one from Nov 2009.

Bulk Samples

The first bulk sample ever taken from the C2 Vein at Zona Canchete, weighing 4.1 tons, was processed at the Dynacor Mill and was determined to have a grade of 5.84 oz/t gold. This grade was precisely duplicated in a referee sample submitted to ALS Chemex Labs in Lima, Peru.

The C2 Vein has been traced on surface for a strike length of about 200 meters. It trends north-northwest and dips steeply (75 degrees) to the east. Based on 31 channel samples previously collected from shallow pits, the vein is 5.0 to 30.0 cm wide (average 12 cm) with assays ranging from 0.03 to 2.60 oz/t gold (average 0.43 oz/t gold). The bulk sample, taken from an adit driven into the northern end of the vein, is substantially higher grade than would have been predicted from the near-surface sampling results.

The C2 Vein appears to be similar to the A4 Vein in Zona Central (some 700 meters to the south) in that the strikes and dips are the same, and the veins are characterized by moderate-grade material punctuated by high-grade "bonanza" shoots that seldom are evident based on assays from shallow pits. This is quite distinct from the east-trending veins at Zona Canchete (C1, C3, and C4), which are sub-vertical structures with consistent and higher-grade gold assays (typically 1.0 oz/t), but lacking high-grade "bonanza" shoots.
