Rye Patch Gold Announces Florida Canyon Q4 2017 Production
- 10,470 OUNCES OF GOLD PRODUCED
- 4,069 OUNCES OF GOLD PRODUCED IN DECEMBER
- COMMERCIAL PRODUCTION ACHIEVED IN DECEMBER
VANCOUVER, Jan. 9, 2018 /CNW/ - Rye Patch Gold Corp. (TSX.V: RPM; OTCQX: RPMGF; FWB: 5TN) (the "Company" or "Rye Patch") reports Q4 2017 production metrics at the Company's flagship Florida Canyon mine in Pershing County, Nevada.
Production highlights for Q4 2017 as compared to Q3 2017 and the Company's preliminary economic assessment "Plan" (see description below) are:
- Produced 10,470 ounces of gold and 5,447 ounces of silver in Q4;
- Mined 2,372,000 tons of ore (30 percent above Plan);
- Crushed 2,291,000 tons of ore (27 percent above Plan);
- Placed 25,434 ounces of gold on the pad;
- Maintained a consistent gold grade of 0.011 opt including over liner material; and
- Realized a stripping ratio of 0.55 which is significantly lower than Plan.
Gold production continued its upward trend, increasing 31 percent in Q4 compared to Q3. In December, gold production was 4,069 ounces of gold and 1,996 ounces of silver. Total precious metal production for the fourth quarter was 10,470 ounces of gold and 5,447 ounces of silver.
Gold sales benefitted from a combination of selling into the forward sales contract and spot price with a realized gold price of $1,278. Silver was sold at spot price during the quarter and realized an average price of $16.65. A total of 9,532 ounces of gold and 6,756 ounces of silver were sold during the quarter.
Mining and crushing rates are now consistently outperforming the original Plan by 30 percent and 27 percent respectively. As a consequence, the crusher throughput has been increased to 750,000 tons per month of ore crushed and stacked to the South Heap Leap Pad on a go-forward-basis, representing a 25 percent increase over the original Plan. The crusher continues to demonstrate operational performance above 750,000 tons per month, and a study to determine the optimal throughput and associated capital requirements will be completed in 2018.
The waste to ore stripping ratio of 0.55 continues to be much lower than 1.47 projected in the original Plan. The mine is realizing better continuity of grade and tonnage than forecast in the block model. An average of 17 percent increase in ore tons, a 7 percent increase in gold grade, and a 25 percent increase in gold ounces as compared to the resource block model has been achieved. As a result of internal revisions to Florida Canyon's mining plan and changes to the production sequencing, the Company will be using an average stripping ratio 0.8 as a guide for 2018 and an overall stripping ratio of 1.05 for the life-of-mine schedule.
Gold ounces placed on the pad averaged 8,478 ounces of gold placed per month in Q4. Projected recoveries of 71 percent remain consistent with gold recoveries achieved to date. Based on gold ounces stacked and gold ounces poured, the South Heap Leach Pad (SHLP) is performing with 70 percent of the recoverable gold ounces being produced from the primary leach cycle. The remaining 30 percent will be produced during secondary and tertiary leach cycles. To date, only primary leaching has occurred to maximize cash flow and determine the optimal leach cycle. Primary, secondary and tertiary leach cycles will begin in 2018 as the second lifts of ore are placed on top of the first lift.
Based on the Company's six months of operating experience, differences have become apparent between current gold production and that forecast under the Plan. These differences relate to the six-month construction/weather delay, the operational challenges associated with the mining fleet in Q1 and Q2, and a recognition that the process of putting tons under leach to the production of gold dore' takes 60 days. This impacts solely the timing of gold production, not the amount of gold which is ultimately produced.

All four newly purchased CAT 785C haulage trucks are in operation. In addition, the planned Carbon-in-Column (CIC) plant expansion is complete. The newly installed second CIC plant will nearly double the processing capacity with throughput increasing from 18,000 solution tons per day to 30,000 solution tons per day. The additional flow will allow for more square footage to come under leach and increase gold production. The additional CIC capacity will be operational in early Q1 of 2018.
Based on the above planned operational performance of the mine and the crusher and the actual versus model recovery and predictability of the South Heap Leach Pad, the Company has determined that the Florida Canyon mine achieved commercial production in December 2017.
"Plan" refers to the Company's preliminary economic assessment effective March 16, 2016, and dated January 27, 2017, titled "Amended Technical Report – Preliminary Economic Assessment for the Florida Canyon Mine, Pershing County, Nevada" available on the Company's website and under the Company's profile at www.sedar.com.
