Father's Day Vein Yields 24,000 Ounces of Gold Worth $38 million

Updated estimate of over 24,000 ounces is more than double initial estimate of 9,250 ounces

TORONTO, Sept. 20, 2018 /CNW/ - RNC Minerals (TSX: RNX) ("RNC") is pleased to announce an updated estimate of gold production from the "Father's Day Vein" discovery at its Beta Hunt Mine (see RNC news releases dated September 9 and 16, 2018). It is now estimated that 24,000 ounces of high-grade gold has been produced from development on the 15 level at the Beta Hunt Mine. The updated estimate includes additional in-process material from the initial discovery area, specimen stones and coarse gold recovered from the expanded development area (see RNC news release dated September 16, 2018), and an increase in production over original estimates based on final out-turns received from the Perth Mint. Estimated production from the Father's Day Vein is expected to increase as the remaining material from the expanded development area is processed and development continues to be extended. Final gold ounces from the discovery area will be determined after the remaining coarse gold and specimens are processed and/or sold over the short term. All of the high grade coarse gold is being processed by the Perth Mint.

"The cash flow from this massive increase in gold production from the Father's Day Vein at Beta Hunt will fundamentally improve RNC's balance sheet to a substantial net cash position, which will allow RNC to begin to aggressively explore the largely untested high-grade gold potential at Beta Hunt. With ongoing development activities based on an improved understanding of the sediment structures, we expect to provide timely updates on this important discovery. I greatly appreciate the hard work and perseverance of the entire Beta Hunt team, who made this discovery possible, and their ongoing diligence in moving the operation forward." said Mark Selby, President and CEO of RNC.
