TORONTO, June 01, 2021 (GLOBE NEWSWIRE) -- Probe Metals Inc. (TSX-V: PRB) (OTCQB: PROBF) (“Probe” or the “Company”) is pleased to announce the release of an Updated Resource Estimate for its Val-d’Or East project (the “Project”) located near Val-d’Or, Quebec. The estimate includes resources from the Company’s 100%-owned Pascalis, Monique and Courvan properties as well as its option property, Cadillac Break East. With the discovery and the expansion of the gold zones, the mineral resources have shown significant improvement over the previous resource estimate and remain open for future expansion. The current resource stands at 1,773,500 ounces of gold in the Measured & Indicated category (“M&I”) and 2,205,300 ounces of gold in the Inferred category. Drilling was successful in converting an additional 907,200 ounces to the M&I category from the previous resource estimate. This resource estimate was independently prepared by GoldMinds Geoservices Inc. in accordance with National Instrument 43-101 (“NI 43-101”) and is June 1, 2021. Drills will be active throughout 2021 on further expansion, infill drilling and regional exploration. 

David Palmer, President and CEO of Probe, states, “This new resource marks the graduation of Val-d’Or East from an exploration project to a potential mining project with tremendous upside for additional growth. The resource shows a significant improvement from previous estimates not only in size but also in the quality of its ounces. The amount of measured and indicated resource, a project’s best gauge of mineability, has more than doubled, while overall grade has also increased substantially. Monique has been the standout performer this year, showing excellent advances in both resource size and quality with almost all of the ounces identified on the mining lease, while Courvan and Pascalis have seen improvement in quality and grade. This current resource estimate will not only form an excellent base for our upcoming PEA, but will also guide us towards future exploration as we continue to grow and advance this project”.
        
Yves Dessureault, COO of Probe, states, “Our goal for this resource was to highlight Val-d’Or East’s potential as a development project and we have been extremely successful in demonstrating this. We have increased the size, grade and confidence of our total resource and our M&I ounces have now reached a critical mass that could support a robust mining operation. We have worked with GoldMinds and Ausenco to incorporate as much mining engineering concepts into our updated resource estimate and thus maximize the conversion of this resource estimate into mineable resources that will be part of the upcoming PEA integrated mine plan. We are now able to conceptualize an economically viable scale of mine throughput and mine life, and have identified a number of project opportunities, such as ore sorting, which could add significant value to an operation by capturing marginal ore that otherwise would be lost to the waste piles. Val-d’Or East is located in one of the most well-established, mining-friendly jurisdictions in the world and with these results we are eager to advance our project through economic studies”.

The Company has demonstrated with a series of performance tests that the ore sorting technology works very well with the type of mineralization found on the Val-d’Or East project. By applying ore sorting to mineralized waste with very conservative gold recoveries additional mineral material may be extracted from the mineralized waste and thus become additional mineral resource on the Project.

^{Notes:
1 Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market or other relevant issues. The quantity and grade of reported inferred Resources are uncertain in nature and there has not been sufficient work to define these inferred resources as indicated or measured resources.
2 The database used for this mineral estimate includes drill results obtained from historical to the recent 2020 drill program.
3 The pit-constrained updated Mineral Resources are reported at a cut-off grade of 0.42g/t Au for the Monique deposit and 0.40g/t for the other deposits. These cut-offs were calculated at a gold price of US$1,600 with an exchange rate of 1.333 US$/C$ per troy ounce. They were based on the following parameters: mining cost 3.00 or 3.50$/t, processing + G&A costs $21.50/t, transport cost to the central processing facility based on distance on existing roads @ $0.15/t.km, Au recovery 95%, pit slopes from 48° to 59° as per the press release of February 23rd, 2021.
4 The underground Mineral Resources were based on two main mining methods, long-hole retreat at $82/t depending on width of stopes, and mechanized cut & fill at $110/t and the same above ground unit cost as for the pit-constrained scenario, resulting in cut-off grades of 1.65 and 2.05 g/t Au. These cut-off grades were then used to delineate continuous underground mineral shapes above the calculated cut-off grades. Blocks within those UG mineral shapes that are below the cut-off were included as dilution material and the grade reported represents the average of all UG mineral shapes thus delineated.
5 The geological interpretation of the deposits was based on lithologies and the observation that mineralized domains occur either within or proximal to sub-vertical dykes, deformation zones or as low dipping quartz tourmaline vein sets.
6 The mineral resource presented here were estimated with a block size of 5m X 5m X 5m for the Monique pit-constrained Mineral Resource and a block size of 2.5m X 2.5m X 2.5m for all others.
7 The blocks were interpolated from equal length composites calculated from the mineralized intervals. Prior to compositing, high-grade gold assays were capped (capping maximum ranges from 28 to 100 g/t Au depending on the deposit). Depending on the deposit, the composites were 1.0 metre or 1.5 metres.
8 The mineral estimation was completed using the inverse distance to the square methodology utilizing three passes.   For each pass, search ellipsoids followed the geological interpretation trends were used.
9 The Mineral Resources have been classified under the guidelines of the CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council (2019), and procedures for classifying the reported Mineral Resources were undertaken within the context of the Canadian Securities Administrators NI 43-101.
10 In order to accurately estimate the resources, underground voids (shaft, ramp and drifts) and the existing pits were subtracted from the mineralized bodies modeled prior to the pit optimization.
11 Tonnage estimates are based on measured rock densities by Gold Trend. 2.82 tonnes per cubic metre for the Courvan Gold Trend, 2.83 for the Pascalis Gold Trend and 2.88 for the Monique Gold Trend. Results are presented undiluted and in situ for the pit-constrained resources and diluted for the UG resources.
12 This mineral resource estimate is dated June 1, 2021 and the cut-off date for the drillhole database used to produce this updated mineral resource estimate is May 8, 2021. Tonnages and ounces in the tables are rounded to nearest thousand and hundred respectively. Numbers may not total due to rounding.
13 Additional details will be provided in the technical report.}

Additions to the Current Resource Estimate Relative to the 2019 Resource Estimate

The 2019 mineral resource estimate hosted a NI 43-101 resource of 0.87M ounces of gold Measured & Indicated and 2.56M ounces of gold Inferred. A total of 74,662 metres has been drilled since this Resource Estimate. Using a gold price of USD $1,600 per ounce, the updated NI 43-101 mineral resource hosts 1.77M ounces of gold measured and indicated, and 2.21M ounces gold inferred, net to Probe, representing an increase of 16% in total size and an increase of 105% in the M&I category. A total of 84% of the new, 2021, M&I resources are pit-constrained.

2 The above table includes the deposits in the Pascalis Gold Trend, the Monique Gold Trend, the Courvan Gold Trend, Lapaska and Senore. Since the cut-off grades are sometimes difference for these deposits (0.40g/t for Courvan and Pascalis, 0.42g/t for Monique and 0.50g/t for Lapaska and Senore), the totals cannot be directly correlated with the data in Tables 1 to 3.}

Resource Estimation Methodology and Parameters

As part of the resource estimation process, the Company and GoldMinds compiled, verified and modelled all technical information available from the Project, including 3,005 drill hole collars consisting of 319,729 gold assays, which represented 643,439.94 metres of drilling. 3D geological models were built for sub-vertical structures and shallow dipping veins and included key structures hosting and constraining gold mineralization along the Pascalis Gold Trend (New Beliveau, North Zone and Highway deposits), the Monique Gold Trend and Courvan Gold Trend (Southwest, Southeast, Bordure, Bussiere and Creek deposits).

Next Steps

A technical report with respect to the latest mineral resource estimate disclosed today will be filed within 45 days in accordance with NI 43-101. The resource estimate will be the basis for the ongoing PEA to be released in Q3-2021.
