Message: trenching

I believe the presentation of the trenching results in the fashion below, leaves a lot to be desired.Our trenching started May 17/2011 http://steliasmines.com/newsrelease/extensive-trenching-program-commencing-at-the-tesoro-gold-project-in-peru/

By May 31/2011, 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. http://steliasmines.com/newsrelease/diamond-drilling-tesoro-gold-project-in-peru/

Then you see, on July 26/2012, over a year later, 4250 m completed in total with 557 samples taken total.

As you can see below, these are supposed to be the complete trenching results. If you look at the manner in which they are presented, there is no vein count, no mention of anomalous placer gold, which could skew results, regardless whether it was encountered or not, there is no distinction made, and there were references in historic data in the past that mentions anomalous gold, not sure if it was soil encountered, host rock encountered, or float encountered. The point being, as per above, the first trenching was done on a systematic grid like program of 5m intervals. The problem exists that the reader cannot distinguish what was sampled, where it was sampled, ie, veins, soil or host rock. Also there is very little to help locate or position where the grid was taken. Too much lack of info, for even the brightest geo to offer an opinion on this type of presentation, because relevant info is not included, that an investor would need to make a reasonable investment decision. To stress the point, there could be a large open pit surface hidden in these results, and no one would ever know because of the lack of information. A couple or three bad results on the end of the grid line, could severly diminish the grade of the average.

The tables below are useless, because an average grade across, god knows what widths, is applied. You cannot do this in a sampling project to get any reasonable representation of strip or open pittable mining widths. We know from historical data, that the Tesoro has alteration zones of at least 50m wide, and quite possibly a lot wider, because the regional geology allows for wide shear zones , numerous gradients and wide areas of vein alteration, which, in high enough grade, becomes open pittable.

A quick look at the vein portion of the table below says nothing, because there is no info there, no maps, etc. We know there are many veins on the Tesoro, but no distinction if these are new veins, known veins, or half and half, etc. We don,t know the distances between these veins, etc, important factors needed to try and figure a resource, and I believe that type of info should not be with held from investors, especially at a time when our sp has been decimated and a proposed PP that came without giving full details of the trenching results to the public.

I would like to know if any exchange geos looked over this release?

The Company has also completed a mechanized trenching program on the Property. A total of approximately 4,250 linear meters of trenching in 66 trenches were completed. 557 samples, from the wall rock and quartz veins, were collected and submitted for analysis from these trenches. The majority of the trenching was completed in the area between Zona Central and Zona Sur.
