ROXGOLD ANNOUNCES RESULTS FOR METALLURGICAL TESTWORK DRILLING
Toronto, Ontario, (May 02, 2013) Roxgold Inc. (ROG-TSX.V) (“Roxgold” or the “Company”) is pleased to announce results from metallurgical drilling at its 100% owned Yaramoko Permit in Burkina Faso.
HIGHLIGHTS:
• 29.73 grams per tonne (“gpt”) gold over 28.8 meters in metallurgical test hole,
YRM-13-MET-01
• 27.62 gpt gold over 7.3 meters in metallurgical test hole, YRM-13-MET-05
“The results from the metallurgical test holes released today are in line with what we expect from the 55 Zone,” stated Paul Criddle, COO of Roxgold Inc. “Hole YRM-13-MET-01 provides confirmation as to the continuity of grade over an approximately 25 meter vertical slice through the deposit. Results such as these continue to validate our confidence in the 55 Zone and we look forward to conducting the next phase of test work as part of our Preliminary Economic Assessment. ”
Metallurgical test drilling commenced in late March and samples gathered from these holes have been dispatched to Canada for Phase II metallurgical test work. The work will be conducted on behalf of Roxgold by Met-Solve Laboratories Inc. of Vancouver, British Colombia.
The metallurgical test holes were intentionally designed to drill down-dip on the 55 Zone structure in order to gather representative samples of mineralized material for metallurgical testing. Drill hole YRM-13-MET-01 was drilled on section 9475 and intersected 28.80 metres of mineralized material at approximately 200 meters vertical depth. The hole did not completely pass through the zone and was terminated in the footwall. Holes YRM-13-MET-02 and 03 were planned to test mineralization at approximately 60 to 100 meters. Both holes ended up drilling under the structure and paralleling the 55 Zone at 64 and 63 degrees respectively. The dip angles for holes YRM-13-MET-04 and 05 were flattened to 55 degrees and both intersected the 55 Zone structure as planned, estimated true widths on holes MET-04 and MET-05 are 1.70 meters and 1.85 meters respectively. In total 980 meters of HQ drill core in 5 holes were completed for this program. Click here for a longitudinal section of these results

In total, 170 kilograms of material was collected and dispatched for test work. This sample material will be split into granite and quartz and volcanic and quartz domains for test work. The phase 2 test work program will consist of the following:
- • Hardness and Abrasion Testing (Bond Indices)
- • Gravity gold characterisation (GRG testing)
- • Grind sensitivity - cyanide (whole ore) leaching
- • Diagnostic Leaching Tests
- • Settling and Reagent consumption tests
Results from these tests will feed into Roxgold’s Preliminary Economic Assessment (“PEA”) study that is scheduled to be completed in Q3 2013.
