Gold Reach Announces Positive Metallurgical Results From The West Seel Deposit


May 14, 2014

May 14, 2014: Vancouver, British Columbia: Gold Reach Resources Ltd. (GRV: TSX-V) (Gold Reach and/or the Company) is pleased to announce results of metallurgical test work conducted on a large composite sample from the West Seel deposit at the company’s 100% owned Ootsa Property, located adjacent to the producing Huckleberry Mine south of Smithers, British Columbia.

HIGHLIGHTS

  • Excellent Overall Metallurgical Results – The West Seel deposit shows very good metallurgical results by conventional froth flotation recovery methods, with rougher flotation recoveries up to 95.1% for copper and 94.5% for molybdenum.
  • Rapid Flotation Kinetics at West Seel – The flotation kinetics of the West Seel material are rapid achieving >91% copper and molybdenum recoveries after only 6 minutes of flotation in a laboratory cell.  
  • Copper Concentrate – A copper concentrate containing 24.3% copper, 8.92 g/t gold, and 200.9 g/t silver was obtained after 2 cleaning stages with overall recoveries of 89.2% for copper, 75.7% for gold, and 79.2% for silver.
  • Molybdenum Concentrate – A molybdenum concentrate grading 51.9% molybdenum was produced after 2 cleaning stages with overall molybdenum recovery of 79.7%.

Metallurgical Studies

Metallurgical testing was performed by Inspectorate Exploration and Mining Services Ltd. located in Richmond British Columbia, and advanced testing was done on a 314 kilogram single composite representative sample from 2013 drill core from the West Seel deposit.  Test grinding was performed and two batch rougher and two batch rougher-cleaner tests were completed to verify the metallurgy of the new sample and optimize the reagent scheme.  An optimized copper concentrate was produced and two molybdenum separation tests were performed.

Overall the West Seel composite has very similar metallurgical characteristics as the Ox and East Seel deposits, however, the flotation kinetics of the West Seel sample were comparatively faster, achieving >91% Cu and Mo recoveries after only 6 minutes of flotation in a laboratory cell.  Results for 2 rougher flotation tests are summarized below.  The best recoveries of copper and molybdenum were 95.1 and 94.5%, respectively in test F2.

A pyrite scavenger flotation test was conducted and resulted in an additional 17% gold recovery in test F1, bringing total gold recovery up to 83.1% in that sample. This is a very significant increase in gold recovery for the West Seel deposit, which contains a pit constrained total of 409,000 ounces of gold in the measured and indicated categories plus an additional 1.1 million ounces of gold in the inferred category.  A gold mineralogical study is underway to better understand the mineral associations and liberation size of gold in the sulphide matrix, and this information may help optimize gold recoveries.  A copper separation test resulted in a 2nd cleaner stage concentrate grading 24.3% copper, 8.92 g/t gold, and 200.9 g/t silver with overall recoveries of 89.2% for copper, 75.7% for gold, and 79.2% for silver.

A molybdenum separation test resulted in a 2nd cleaner stage concentrate grading 51.9% molybdenum with an overall molybdenum recovery of 79.7%.  A third cleaning stage resulted in a molybdenum concentrate grade of 53.6%, however, overall molybdenum recovery was reduced to 54.9%.  It was therefore recommended that only two stages of cleaning be employed in the molybdenum circuit.

Based on the current metallurgical test work the predicted metallurgical recoveries are summarized in the table below.  The West Seel deposit shows excellent copper recovery at 92.1% with molybdenum, gold, and silver recoveries in line with operating porphyry deposits.  With the pyrite concentrate included, the overall recovery for gold would increase to 72.2% and for silver to 60.7%.   Further test work on a larger sample, perhaps a pilot plant trial, would allow locked-cycle tests to be run to see how recirculating tails might increase overall recoveries.

Dr. Shane Ebert, President of the company stated, “metallurgical test work has now confirmed that excellent recoveries are achievable at all three deposits on the Ootsa project by industry standard processing techniques, and additional test work might be able to increases recoveries even further.  The metallurgy of the West Seel deposit appears to be simple and copper and molybdenum separation can be achieved very rapidly. These positive metallurgical results continue to remove project risk as the company advances the Ootsa project towards preliminary economics”.

Plans for 2014

Planning for the 2014 exploration program at Ootsa is underway and drilling is scheduled to commence during the first week of June.   The focus for 2014 will be to optimize the economic potential of the project through expanding known zones of higher grade mineralization at the West Seel deposit, and for the first time targeting several high grade silver base metal veins.  In addition several porphyry copper exploration targets surrounding the Ox and Seel deposits will be tested.
