TRES-OR DIAMOND INDICATOR MINERAL RESULTS FROM THE GUIGUES KIMBERLITE PIPE IN QUEBEC
Vancouver, B.C. – December 14, 2020 - Tres-Or Resources Ltd. (“Tres-Or” or the “Company”) (TSXV: TRS, OTCPK: TRSFF) is encouraged by the diamond indicator mineral chemistry reported from samples of Guigues drill core sent to C.F. Mineral Research Limited, an ISO 9001:2015 certified/ISO 17025:2005 compliant laboratory in Kelowna, B.C.
C.F. Minerals, hand-picked over 8,000 indicator minerals and then selected 701 for new microprobe analyses. The analyzed indicator minerals include eclogite and pyropes garnets, chromite, chrome diopside, picroilmenite, and olivine recovered from different parts of the pipe (Table 1). The new microprobe results support Tres-Or’s previous interpretation of a mantle indicator mineral signature comparable to the Victor kimberlite, especially in regards to having numerous eclogitic and lherzolitic garnets with compositions similar to diamond inclusions at Victor (Stachel, et al., 2020). C.F. Minerals also examined sample residues for microdiamonds, recovering 5 natural stones, all less than 106 microns in size.
In total, the 3 samples weighed 393.34 kgs and after arrival in Kelowna and were disaggregated by attrition milling, with the +106 micron material concentrated by density and magnetic properties.

The highly encouraging indicator mineral chemistry at Guigues is closely similar to De Beers’ Victor Diamond Mine, and differs from the standard model for diamond exploration. The Guigues Kimberlite diamond potential, like that of the Victor Diamond Mine, is based on high-priority source of diamonds from mantle eclogite and lherzolite rocks, instead of the standard harzburgite (G10) sources. The potential diamond source for Guigues is marked by recovery of eclogite and lherzolite garnets that have distinctive compositions just like diamond inclusions recently described from Victor by Stachel et al. (2018). The Guigues Kimberlite yields numerous lherzolite and eclogite garnets of comparable diamond inclusion composition, as recently confirmed by application of CF Mineral Research Laboratory’s updated classification system by owner and originator Dr. Charles Fipke.
The overlay of the fields for Victor’s lherzolitic and eclogitic diamond inclusions with those from the Guigues Kimberlite shows the strong similarities between garnet populations (Figure 1).
Eclogite garnet inclusions from Victor (analyses below 0.75% Cr2O3 above) show a strong population of low titanium and increasing sodium, similar to eclogite garnet inclusions from around the world, including Victor (Figure 2).
Microdiamond counts were reported in Tres-Or’s news release dated November 9, 2020 using modern microdiamond methods at the Saskatchewan Research Council Geoanalytical Laboratories Diamond Services (SRC). In total, 6 of the sample bags yielded between 1 and 4 microdiamonds each (27 bags (8 kg each) analyzed), consistent with reasonably widespread distribution of diamonds throughout the tested kimberlite intervals. In other words the microdiamonds were not derived from just one or two places, as might happen with a single stone crushed during sampling, or a group of stones from a single diamond-bearing mantle xenolith.
Three (3) additional samples of approximately the same sizes but from distant parts of the Guigues pipe are currently being processed for microdiamond content at SRC. Results, including counts and nitrogen contents, will be reported as soon as available. This work together with the initial microdiamond analyses testing program results will provide additional data for further follow-up exploration work recommendations.
See Tres-Or’s website (www.tres-or.com) for more details on the Guigues Kimberlite Pipe.
Note that although the indicator mineral chemistry is closely similar to the Victor Diamond Mine, and the microdiamond results reported point towards potential to carry larger stones (refer to Type II microdiamonds recovered from Guigues as reported in Tres-Or’s news release dated December 8, 2020), this does not necessarily mean the Guigues Kimberlite will host diamonds of economic size. Tres-Or’s ongoing microdiamond tests are expected to better define the potential to host economic diamonds.
