We all know we've been waiting long & patient for the Trenching results. I am very much looking forward to seeing those numbers, even more so now. I was going over the homepage, and if you look under Projects, then under Tesoro, and scroll down, you'll see a section on trenching.

I'm not sure if you're all aware, but it's worth a read. They did a very small trenching program between the Quantec phases. Anyway, I've read this many times now, but today, I took it a little further. Did some math on it.

This is the 1st paragraph from that section on Trenching:

Upon receipt of Stage 1 preliminary Titan24 geophysical sections generated in the field, a small trench-sampling program was completed across a geophysical anomaly corresponding to the “structural corridor” in the vicinity of the A4 Vein in Zona Central. Twenty-two 3m-long bulk samples weighing about 30kg each were collected from 3 trenches testing a 100m strike length of the low-resistivity geophysical response. The trenches were aligned perpendicular to the long axis of one distinct low-resistivity anomaly and returned 50 to 1130ppb (1.13g/t) gold across an alteration zone up to 45 meters wide, including economically significant assays of 553 ppb gold across 9 meters (3 samples). The zone tested by trenching is 100 meters long, and further work is required to evaluate the much longer strike length indicated by geophysical responses.

So think about, because I finally did today!

22 samples, that were 3M long, and weighed approx 30KG each

30KG might seem like a bit of weight, but lets think about it. We know it's 3M long, but we don't know the width, or depth. But we do know the host rock is approx 2.75T/M3

So, that's 2750KG/M3 I won't show all the Math, but that leaves you with the following, approx:

6cm X 6cm X 3M X 2.75T/M3 would give you that 30KG bag

So, my point is, imagine 6cm by 6cm, yes that is very small. When you look at the A4 area, approx Line L4750 - L5000, you see many veins on the images. These veins, on average are approx 100M apart. So, sampling such a very small area, what really are we sampling? And, they still got some very nice results from it. Basically equalled the Yanacocha cuttoff grade.

So, imagine when we get the results from the extensive trenching program, announced on May 17 & June 09, and include a much bigger area, and I'm sure also include many of these very rich narrow veins? I'm thinking the results will be much better, than the already good results!

As at May 31, 2011, 15 trenches totalling 1,200 linear metres have been completed with 215 samples collected over 5m sample intervals from the trenches at the Tesoro Project. The trenches were completed by a backhoe and a track-mounted excavator at Zona Central (Main Structural Corridor) and Zona Este (Parallel Structural Corridor).
