Santacruz Silver Mining reports fatality at Tres Amigos mine in Bolivia
Tres Amigos mine, a part of the Caballo Blanco Group of mines, has resumed operations after it was shut down following the incident.
VANCOUVER, BRITISH COLUMBIA–(Marketwire – Sept. 13, 2011) – ATAC Resources Ltd. (TSX VENTURE:ATC) is pleased to announce the final 2011 drill results from its Ocelot silver-lead-zinc discovery. The Ocelot is located within the Rau Trend in the western portion of ATAC’s 100% owned Rackla Gold Project in the Keno Hill Mining District, Canada’s second largest primary silver producer.
The 2011 diamond drilling program consisted of 19 holes totaling 3784.75 m. The first five holes returned encouraging results near surface (see news release dated June 13, 2011). Additional drilling was conducted along strike and down dip from these initial diamond drill holes. Significant results from the remaining 14 holes are tabulated below.

| Reported intersections are drilled thicknesses. True widths are estimated to be 50 to 60% of the reported drill intervals. | ||||||||
Holes OC-11-15 and 19 through 24 did not intersect significant mineralization. Hole 15 was collared too far forward on section and tested above the mineralized zone while holes 19 through 24 tested the mineralizing structure along strike to the southwest. A plan view of the Ocelot drill holes can be viewed on ATAC’s website, www.atacresources.com. All drill holes in this release are presented in cross-sectional and 3-D views at www.corebox.net, with a link also available on ATAC’s website.
Mineralization at Ocelot consists of medium to coarse grained pyrite and varying concentrations of low iron sphalerite and medium to coarse grained galena. Sulphide mineralization occurs within a steeply dipping northeast trending fault that cuts an extensive dolomite sequence locally exhibiting structural and fluidized breccias. Drilling to date has identified mineralization over a 230 m strike length and to a depth of 150 m. Mineralization remains open downdip and along strike to the northeast.
ATAC intends to carry out ground geophysical surveys in the spring of 2012 to determine if additional zones of mineralization similar to Ocelot are associated with several untested natural spring gossans in the area.
QA/QC
All analyses for the 2011 program are being performed by ALS Chemex with sample preparation in Whitehorse and assays and geochemical analyses in North Vancouver. All core samples are initially analyzed for gold by fire assay followed by atomic absorption (Au-AA26) and 48 other elements by inductively coupled plasma-mass spectrometry (ME-MS61). Samples in mineralized intervals are assayed for silver, lead and zinc by inductively coupled plasma – atomic emission spectroscopy (Ag/Pb/Zn-OG62).
Rigorous procedures are in place regarding sample collection, chain of custody and data entry. Certified assay standards, duplicate samples and blanks are routinely inserted into the sample stream to ensure integrity of the assay process.
