Goldsource Provides Q4 2016 Production Results; Plans for 2017






Goldsource Mines Inc. (TSXV: GXS) (OTCBB: GXSFF) (FWB: G5M) announces the fourth quarter and annual production results for the year ending December 31, 2016 and development plans for 2017 at its Eagle Mountain Gold Project located in Guyana, South America.



Eagle Mountain Production Highlights Q4, 2016 vs Q3, 2016


  • Processed 39,513 tonnes; 13% increase.
  • Average throughput of 527 tpd; 13% increase.
  • Estimated gravity recovery to concentrate of 27%; 8% increase.
  • 253 gold ounces produced; 45% increase.
  • 353.3 gold ounces sold; 425% increase.



Ioannis Tsitos, President, commented, “We continue to make improvements at Eagle Mountain by increasing throughput and gold recovery through our optimization program with the goal of achieving free cash flow from operations. In Q4, throughput increased 13% and plant recoveries increased by 8% which, when combined with improved mine grades, led to a gold production increase of 45% compared to previous quarter. The process plant (“Main Plant”) was shut down on December 23rd for equipment installation including replacement of pipelines, pumps and a Krebs cyclone which should further increase throughput and recovery in early 2017. Beginning early February we plan to operate a low cost “Secondary” gravity operation and reduce corporate and in-country costs to supplement cash flow. Overall, 2016 was a challenging year with a variety of factors affecting throughput and lower than expected recovery. Management remains optimistic that the initiatives scheduled in early 2017 will further address the throughput and recovery issues. In association with ongoing work, we will consider permitting a substantially larger operation supported by a planned expansion of saprolite resources.”

During Q4, 2016, Eagle Mountain processed 39,513 tonnes of material (Q3, 2016: 35,043 tonnes), with an average of 527 tpd (Q3, 2016: 467 tpd) grading 0.98 gpt gold. As previously announced in the Company’s revised production guidance (see news release dated November 14, 2016), operations in the second half of the year were interrupted by equipment delivery delays, faulty pumps, and drought conditions. In November, the process was altered to bypass the recirculation of plus 2mm oversize material and to stockpile it in inventory. This significantly decreased plant maintenance requirements with less downtime and improved throughput. By mid-December, operations were running continuously at near capacity. In December (to the 23rd), the mine operated for 18 days, processing 12,497 tonnes of material at an average throughput rate of 694 tonnes per day. Estimated gravity recovery to concentrate averaged 27% for Q4, 2016 (Q3, 2016: 25%).



In Q4, 2016, the Company poured 253.0 ounces of gold and sold 353.3 ounces of gold at an average realized price of US$1,232 per ounce.



While onsite management was able to incrementally improve gravity gold recovery to concentrate in Q4 to 27% (up from 25% in Q3), the recovery rate remains well below design of 35-40% for a gravity only operation. As a result, the Main Plant at Eagle Mountain was shut down on December 23, 2016 and one half of the workforce at Eagle Mountain was released to reduce in country costs while the Company completes further plant modifications intended to improve throughput and recovery.



In 2017, Goldsource plans to:


  • Install a Krebs cyclone in the Main Plant to de-slime the scrubbed material prior to gravity recovery through the Falcon concentrators. This should result in a significant improvement in the recovery of fine gold to concentrate. The cyclone delivery to Eagle Mountain is scheduled for late January, with the goal of restarting of the Main Plant to test for increased recovery in February.
  • Install a HDPE slurry pipeline to replace the current 1,200 metres of PVC pipeline. This should allow the process plant to operate more reliably reducing losses of production due to pipe bursts. The HDPE slurry pipeline is onsite and is being prepared for installation.
  • Install and operate a low cost Secondary gravity operation. The Company is currently making preparations to begin a sluice operation to process colluvium, alluvium and some saprolite gold resources. Set up and initial production for this operation should be completed by late January.
  • Complete a low cost drilling campaign to increase the Company’s current NI 43-101 saprolite (indicated and inferred) resources, which are estimated at 380,000 gold ounces. Drill results may expand the saprolite resource with the goal of supporting a large scale, low strip, gravity-cyanidation operation at Eagle Mountain.
  • Depending on results for saprolite resource expansion in H1, 2017, initiate a Pre-Feasibility Study in late 2017 for a large scale operation. As part of this study, the Company will do further environmental work to start the permitting process for a large scale operation.
