Metallurgical Test Work Indicates Very High Gold Recoveries at Ascot’s Premier Property
TSX VENTURE: AOT
VANCOUVER, British Columbia, Nov. 22, 2018 (GLOBE NEWSWIRE) -- Ascot Resources Ltd (TSX.V: AOT; OTCQX: AOTVF) (“Ascot” or the “Company”) is pleased to announce that confirmatory metallurgical test work on six new composites from the Premier/Northern Lights, Big Missouri and Silver Coin deposits produced outstanding gold recoveries over a range of grind sizes utilizing a gravity and leach process.
Derek White, President and CEO of Ascot Resources commented, “We are very excited about the test results on metallurgical recoveries, grind size and the potential impact of an effective gravity circuit in the milling process. This latest test work was similar in nature to technical work completed in 2015 and achieved excellent gold recoveries. We are incorporating these results into our ongoing engineering studies to quantify the added value to the project.”
In the course of evaluating the restart scenario of the Premier mill, it was decided to conduct confirmatory metallurgical test work to establish parameters for throughput expectations and the recovery of gold and silver. According to Westmin Resources production records from 1989 to 1996, the Premier mill achieved an average gold recovery of 91.1% and a silver recovery of 45.2%. Ascot is planning to refurbish the Premier mill in its original configuration with the exception of adding a centrifugal gravity concentration stage (Knelson concentrator or similar) into the flow sheet.
The 2018 confirmatory test work was conducted at Base Met Labs in Kamloops. The tests included a centrifugal gravity stage, followed by leaching, and achieved an average gold recovery of 97.43% and a silver recovery of 72.67% (see Table 1) at the grind size (54µm) that the Premier mill historically operated at. The test work was conducted on six composites from a variety of mineralized zones from the Premier area, Big Missouri and Silver Coin, covering a grade range from 2.87g/t Au to 9.08g/t Au. Tests were conducted at a variety of grind sizes and demonstrate that gold recovery is not particularly sensitive to a coarser grind size. This provides flexibility to generate different throughput rates during operation by varying grind sizes without a significant negative effect on gold and silver recoveries. The selected composites are designed to represent the zones of mineralization that are likely to be accessed early in a restart scenario.
The addition of a gravity stage into the flow sheet was prompted by test work conducted in 2015 that evaluated gold and silver recovery of three composites from Premier (high grade and low grade) and Big Missouri. Several tests were run with the addition of a gravity stage in the process and these tests achieved higher recoveries than the leach tests without a gravity stage (see Table 2).
The results of the confirmatory metallurgical test work will be utilized in the engineering studies that are currently underway, with additional test work planned in 2019.
Table 1 Metallurgical test results from six composites in the Premier area, Big Missouri and Silver Coin (Base Met Labs, 2018). The results show excellent recoveries for gold with a significant gravity component. The highlighted average values at the bottom of the table are calculated for a primary grind of 54µm. The recoveries at 100µm are slightly lower but still very high compared to historical performance. The final column shows the ball mill work index for each composite. The results are in line with historically observed hardness of processed material.

The gold recovery achieved in the tests with an added gravity stage are higher than the results achieved by leaching only. These results prompted the inclusion of a gravity stage in the current test work.
