Rye Patch Gold Announces Phase-2 Metallurgical Results

Vancouver, British Columbia, March 9, 2016 - Rye Patch Gold Corp (TSX.V: RPM; OTCQX: RPMGF; FWB: 5TN) (the “Company” or “Rye Patch” - https://rohstoff-tv.net/c/mid,3074,Firmenpraesentationen/?v=290183) announces initial results from McClelland Laboratories in Reno, Nevada for the Phase-2, feasibility-level metallurgical test program for Rye Patch’s 100% owned Lincoln Hill Project in Pershing County, Nevada.  Final results have been received for the 18 bottle-roll tests. Specific gravity, work index, and abrasion studies were also completed.  Acid Based Accounting (ABA) studies are in progress.   Column tests are in progress with results pending.

HIGHLIGHTS

·      A total of 6 composites at three different feed sizes were analyzed, and results indicate that gold and silver recoveries are size dependent;

·      The results suggest that Rochester-like gold and silver recoveries are achievable with a crushing circuit.

·      Gold recoveries for the larger sized material can be improved through increased leach time; and

·      Additional work, Phase-3, will be completed to identify the optimum heap leach feed size.

Bottle-roll leach tests were completed on six composites at three different feed sizes. The bottle-roll testing was designed to evaluate gold and silver recoveries at the different feed sizes, and review similarities in rock properties with the adjacent Rochester mine.  The results indicate that recovery is not rock type dependent but show a marked improvement with smaller feed size. The work also suggests higher recoveries could also be achieved from longer leach cycles for the larger feed sizes.  The composites were compiled from six, PQ-size core holes totaling 920 metres (3,337ft.).  Table 1 lists the drillhole interval used in the composites.

Figure 1 illustrates the relationship between particle size and gold recovery.  The graph conclusively shows an increase in gold recovery with smaller particle size.  The next round of testing will determine the optimal size for crush material as well as leach cycle time.  However, the gold liberation from smaller feed sizes suggests the Lincoln Hill material behaves similar to the adjacent Rochester mine.

The gold recoveries show a positive trend with smaller feed size.  The bottle roll results varied from 94.1% to 82.4% for 75µm feed size, and from 57.1% to 29.4% passing for the 50mm size. 

Silver recoveries showed the same increase in recovery with smaller feed size and varied from 90.9% to 76.7% for 75µm to 39.2% to 13.5% for the 50mm size fraction.  Recoveries can be improved for the larger sized material by increasing the leach time and cyanide concentration for silver.

Figure 2 illustrates the relationship between particle size and silver recovery.  Additional metallurgical tests are investigating cyanide concentration and optimum feed size for silver recovery; however, the graph shows a significant inflection point where better recoveries can be achieved for feed sizes below 9.5mm.  The data indicate that silver liberation from smaller feed sizes on Lincoln Hill material behaves similar to the adjacent Rochester mine.

Figure 2: Silver Recovery versus Feed Size

Table 2 shows the gold and silver recovery results for the 18 bottle-roll tests, oxidation and alteration characteristics, and gold grade class.  The low-grade classification is between 0.1 gm/T Au and 0.7 gm/T Au.  High-grade classification is greater than 0.7 gm/T Au.
