Goldsource Mines Inc. is pleased to report the production results for the second quarter and for the first half of 2016 at its Eagle Mountain Gold Project located in Guyana, South America. Phase I of Eagle Mountain is based on a Preliminary Economic Assessment dated June 15, 2014, which calls for a 1,000 tonnes per day (“tpd”) open pit – gravity plant with post-commissioning and ramp up cash operating costs of US$500 to US$600 per ounce of gold. Please refer to the Company’s website at www.goldsourcemines.com and the Company’s filing on SEDAR for further information on the PEA.

Eagle Mountain Production Highlights Q2, 2016 vs Q1, 2016:

• Processed 48,098 tonnes; 450% increase.
• Average throughput of 641 tpd; 296% increase.
• Estimated gravity recovery to concentrate of 47%; 18% increase.

N. Eric Fier, CPG, P.Eng and Chief Operating Officer, commented, “The Eagle Mountain commissioning period and commercial production milestones in H1, 2016 were a challenge on several levels with a tightly constrained initial capital requirement of US$5.9 million, as budgeted in the PEA. With perseverance, our team was able to complete the Phase 1 “Proof of Concept” project under the initial budget. All significant project risks have been minimized for moving forward to increased production with anticipated positive cash flow in H2, 2016.”

During Q2, 2016, Eagle Mountain processed 48,098 processed tonnes, with average of 641 tpd (Q1, 2016: 162 tpd). For the 30 continuous days prior to June 20, 2016, Eagle Mountain processed an average of 916 tpd.

As initially planned, the average grade dropped from 0.91 gpt gold to 0.37 gpt gold while optimizing the plant with lower grade material. Current low grade material is considered pre-strip for mining anticipated higher grade material in Q3, 2016. Estimated average grade for the beginning of July is approximately 0.80 gpt gold at a 0.0:1 strip ratio, transitioning to greater than 1.0 gpt gold in August.

Estimated gravity recovery to concentrate averaged 47% for Q2, 2016 (Q1, 2016: 40%). The increase in recovery was due to optimization of the process plant. H2, 2016 recovery rates are expected to be similar to Q2, 2016.

The Company poured 145.2 ounces of gold and sold 200.3 ounces of gold at an average realized price of US$1,264 per ounce.
