Canamex Resources Reports +90% Gold Extraction From Cyanidation Tests on Samples from Bruner Gold Project, Nye County, Nevada

28.01.2014  |  Marketwire

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan 28, 2014) - Canamex Resources Corp. (the "Company") (TSX VENTURE:CSQ)(OTCQX:CNMXF)(FRANKFURT:CX6) is pleased to announce results from metallurgical tests on drill and bulk samples from the Bruner gold project, Nye County, Nevada.

Bottle Roll Cyanidation Tests

Bottle roll cyanidation tests were performed on composites from two drill holes from the 2013 drilling program. Coarse rejects from drill holes B-1340, a reverse circulation drill hole, and B-1341C, a core hole, were composited into 20-ft composite samples, pulverized to 80% passing -200 mesh, and subjected to bottle roll cyanidation for 96 hours. Hole B-1340 is from the historic resource area and hole B-1341C is from the Penelas East discovery area. The two deposits and drill holes are about one mile apart.

In hole B-1340, intervals from 125-145 feet through 440-460 feet were tested. Gold extractions ranged from 93% to 99% on head grades ranging from 0.0109 opt Au to 0.7072 opt Au, with lower head grades having lower gold extractions and higher head grades having higher gold extractions. Overall the drill hole had an average gold extraction of 97% on an average calculated head grade of 0.1011 opt Au. The average tail grade was 0.0009 opt Au. Average silver extraction was 54% on a calculated head grade of 0.218 opt Ag.

In hole B-1341C, intervals from 250-270 feet through 660-680 feet were tested. Gold extractions ranged from 76% to 99% on head grades ranging from 0.0013 to 0.2074 opt Au, with lower head grades having lower gold extractions and higher head grades realizing higher gold extractions. Overall the drill hole had an average gold extraction of 93% on an average calculated head grade of 0.0296 opt Au. The average tail grade was 0.0010 opt Au. Average silver extraction was 55% on a calculated head grade of 0.218 opt Ag.

There was no decrease in gold or silver extraction with depth in either drill hole. Average cyanide consumption in tests from B-1340 was 0.17 lbs/ton, and average lime consumption for pH control was 2.83 lbs/ton. Average cyanide consumption in tests from B-1341C was 0.22 lbs/ton, and average lime consumption was 3.53 lbs/ton.

Column Leach Tests

Two columns are currently under leach from a bulk sample taken in early December 2013 from the lower (Duluth) adit within the historic resource area. One column is at a -3 inch crush size and the other is at a -3/4 inch crush size, to simulate 1-2 stage and 2-3 stage crushing, respectively, depending upon equipment selection and desired throughput rate. Both columns have been under leach for 19 days. Based upon head grade analyses of 0.0133 opt Au, the -3/4" column is at 65% gold extraction after 19 days and the -3" column is at 48% extraction after 19 days. Both columns will remain under leach for at least 45 days to quantify gold extraction from a lower grade zone within the historic resource area to assist in determining the appropriate cut-off grade for heap leaching.

Greg Hahn Comments

"The results from the metallurgical tests are very encouraging," states Greg Hahn, President and COO. "They demonstrate excellent gold extractions at both the historic and Penelas East deposit areas, and the continuing column leach tests are demonstrating rapid gold extraction from even the lower grade portion of the historic resource area. We are also pleased with the low reagent consumption demonstrated by these test results."

Quality Control

Drill samples were composited and bulk samples were collected by an independent contractor and delivered to Kappes Cassidy & Associates testing facility in Reno, Nevada, where all metallurgical tests are being performed.

Greg Hahn, President and COO and a Certified Professional Geologist (#7122) is the Qualified Person under NI 43-101 responsible for preparing and reviewing the data contained in this press release.
