Vancouver, B.C., May 22, 2020 – Ximen Mining Corp. (TSX.v: XIM) (FRA: 1XMA) (OTCQB: XXMMF) (the “Company” or “Ximen”) is pleased to announce it has received metallurgical test results for its Kenville gold mine in the Nelson mining camp in southern British Columbia.
The Kenville material responded exceptionally well to both gravity and flotation.
The combined gold recovery is 99%,..

The test work started with a sample composited from the Kenville mineralization. Material was sorted on the basis of visible sulphide mineralization and separate lots were assayed. Portions of high-grade and low-grade material were then combined to give a weight average grade approaching the expected grade of material to be mined from Kenville 0.5 ounce per ton gold (17.1 grams per tonne) when the project proceeds to a Bulk Sample. The resultant composite assayed 16.27 grams per tonne gold and 35.60 grams per tonne silver (0.475 ounce per ton gold, 1.0 ounce per ton silver).
The material was then subjected to gravity gold recovery and flotation testing aimed at approximating the process at the target processing plant. The test process involved the following steps:
• Grind to P80 of 150 microns. Conduct PSA.
• Concentrate panned to extinction for Au. Pan tails returned to gravity tailings.
• Rougher-scavenger flotation test on gravity tailings to recover Au. Assay for Au, Ag, and multi-element ICP.
• 3 stages of cleaner flotation. Assay for Au, Ag, and multi-element ICP.
Test results indicate the material responded exceptionally well to both gravity and flotation. The GRG (Gravity Gold Recovery) test achieved an overall gold recovery of 51% in a mass yield of just 0.06% at a gravity concentrate grade of 11,225 g/t Au. Flotation was able to recover 98% of the remaining Au, resulting in a combined overall Au recovery of 99% at a final grind P80 of 147µm. A summary of the test results is given in the following table:
The next step in this study is to submit both the head composite and the final tailings for ABA testing (Acid-Base Accounting) to further characterize the input and product materials.
Kenville Mine Project Update:
Metallurgical test work and results were provided by Sepro Mineral Systems Corp. of Langley, B.C. Assays were performed by MSALABS at Langley, BC, an independent commercial laboratory, accredited with ISO/IEC Standard 17025. Samples were prepared pulverized a 250 gram split to 85% passing 75 microns. Gold analyses were performed on 30 gram subsamples. Sample # 112460 was subjected to a duplicate 30g high grade fire assay (with a detection range of 0.05 – 1000 g/t Au) with gravimetric finish while the remaining samples were each subjected to a single 30g ore grade fire assay (with a detection range of 0.01 to 100 g/t Au) with AA finish.
