VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/19/13 -- Canamex Resources Corp. (the "Company") (TSX VENTURE: CSQ)(OTCQX: CNMXF)(FRANKFURT: CX6) is pleased to announce the results of bottle roll cyanide leach tests on composite coarse reject drill cuttings from two drill holes from the 2012 exploration drilling program on the Penelas East discovery area at the Bruner gold project, Nye County, Nevada.

Bottle Roll Cyanide Leach Test Results

Bottle roll cyanide leach tests returned an average of 97% gold extraction from 21 composites from drill holes B-1201 and B-1207C from the Penelas East discovery area on coarse rejects ground to 80% passing 200 mesh screen size. These tests were run to assess the cyanide solubility from two holes which demonstrated a wide range of grades and vertical extent of gold mineralization within two distinctly different rock types. The positive results indicate that there is no material difference in gold solubility in samples ranging from less than 200 feet below the surface to samples from greater than 500 feet below the surface, no difference in gold solubility between head grades from 0.01 opt Au (0.34 g/t) to 0.64 opt Au (21.94 g/t), and no difference in solubility between gold hosted in strongly silicified quartz rhyolite and partially silicified / argillized volcanic agglomerate. Gold grade of all 21 composites averaged 0.0956 opt Au (3.28 g/t). Leach residue ("tailings") retained on average only 0.001 opt Au (0.034 g/t), ranging from 0.0005 opt Au (0.017 g/t) to 0.0027 opt Au (0.093 g/t), indicating that essentially all of the gold was soluble in cyanide. Although the bottle roll tests were run for 96 hours, almost all of the gold was leached in 24 to 48 hours. Cyanide consumption was very low in all of the bottle roll tests. Silver solubility was encouraging, with an average silver cyanide solubility of 79% at an average head grade of 0.19 opt (6.5 g/t) Ag. Silver is not a strong economic driver at the Bruner project, but these silver extractions bode well for silver contributing to the economics of the project, even at low silver grades.

"We are very encouraged by these metallurgical test results" exclaimed Greg Hahn, President & COO. "These results support the observations of consulting geologist Don White, in his report on logging of core hole B-1207C that the gold-bearing event appears to accompany last-stage fracture filling and to be the latest event at the Penelas East, post-dating at least five previous periods of silica veining or flooding. Thus the gold does not appear to be encapsulated in silica" continued Hahn. "Further, the gold extractions in bottle roll tests from Penelas East are indistinguishable from those performed on the bulk sample from the historic resource area, which returned +85% gold extractions in column leach tests, which bodes well for future column leach tests on the Penelas East discovery area" concluded Hahn.
