TRES-OR ANNOUNCES RECOVERY OF SIGNIFICANTLY MORE MICRODIAMONDS FROM NEW SAMPLES OF THE GUIGUES KIMBERLITE PIPE IN QUEBEC
5-January-2021

Vancouver, B.C. – January 5, 2021 - Tres-Or Resources Ltd. (“Tres-Or” or the “Company”) (TSXV: TRS, OTCPK: TRSFF) is very pleased to announce the recovery of 48 more microdiamonds from new samples of the Guigues Kimberlite pipe in southwestern Quebec, by the Saskatchewan Research Council Geoanalytical Laboratories Diamond Services (SRC). The total of 48 microdiamonds were recovered by SRC from 305 kgs of previously unsampled intervals of Guigues kimberlite drill core, with the largest two microdiamonds remaining on a 0.425 mm square mesh screen (Table 1). All but 3 of the recovered microdiamonds are described by SRC as “White/Colourless, Transparent” with no or minor inclusions. Only one microdiamond is described as having “noticeable inclusions”.

The 305 kgs of material processed for microdiamonds comprise 3 samples from half-split drill core (HQ size) testing different parts of the pipe. Recovered microdiamonds are well distributed throughout the pipe. Out of 65 sample bags processed, 30 returned at least one microdiamond. The maximum number returned per batch was 9 and the second most prolific batch returned 5. The 13 bags comprising sample 047531 returned the most total microdiamonds at 22, suggesting the possibility of a higher grade phase in the southern part of the pipe, but more data is required to gain confidence in this possibility. Tres-Or will be looking to identify potentially higher grade kimberlite phases as additional sample data becomes available.

Each sample was bagged successively by Tres-Or personnel, in approximately 8 kg sub-samples. The total sample interval extends approximately 26 m in length. After bagging and labelling, the samples were delivered to SRC in Saskatoon, Saskatchewan. The unsampled half split of core is stored securely for future reference. The ~8 kg bags were processed by SRC as separate batches and microdiamond recoveries were reported for each of the 8 kg bags. SRC reports microdiamond counts by square mesh screen sizes, increasing successively from the smallest size (in this case 0.075 mm) upwards by a factor of the square root of 2, as specified in CIM reporting standards required under Canadian National Instrument 43-101 reporting standards. SRC also describes and reports dimensions as well as weights for each individual microdiamond.

The abundance of recovered microdiamonds compares well with the first results from SRC, as announced in Tres-Or’s news release of November 9, 2020 (Table 2). The 48 microdiamonds recovered from the new samples average 1.6 per every 10 kgs, which compares favorably to the first SRC microdiamond result which returned 0.5 microdiamonds per every 10 kgs of kimberlite. Part of this apparent increase in abundance is due to recovery of -0.106 to +0.075 mm microdiamonds this time, but even after accounting for those smallest microdiamonds, the new samples returned 1.0 stones per kg compared to 0.5 per kg from the first batch of samples. This increase in abundance may reflect both the larger collective size of the new samples (305 kgs compared to 207 kgs for the first batch) as well as the natural variability in distribution of microdiamonds within the kimberlite.

The combined abundance of microdiamonds (Table 3) compares well with the published results for the Victor Kimberlite (De Beers’ Victor Diamond Mine located 670 km to the northwest of Guigues in the James Bay Lowlands) which Tres-Or considers significant because of the similarities between Victor and Guigues mantle indicator mineral samples (see Tres-Or news releases of November 9, 2020 and December 14, 2020).

Victor microdiamond data in the public domain is limited, with the most detail being provided in a De Beers’ assessment report on Victor and nearby pipes (Winzar, 2001). By adding Guigues total data to that provided in Winzar’s report (2001), Guigues’ microdiamond recovery at 1.1 per 10 kgs compares to Victor at 1.3 per 10 kgs, although the Victor sample was twice as big at 1,080.7 kgs. Note that the reported De Beers data was from work completed before approximately 1996 and did not follow the later CIM reporting standards of specified square mesh screen sizes increasing by a factor of the square root of 2. Note also that although Victor’s published indicator mineral and microdiamond data are both closely similar to Guigues, that work was not done or confirmed by a Qualified Person (QP) working for Tres-Or, nor does it necessarily imply the Guigues pipe has a similar macrodiamond population to the Victor Diamond Mine (although Tres-Or believes Guigues merits further micro- and macrodiamond sampling).
