Monique Deposit Updated NI 43-101 Resource Estimate ("Resource Estimate") Highlights:
TORONTO, Jan. 17, 2023 (GLOBE NEWSWIRE) -- Probe Gold Inc. (TSX-V: PRB) (OTCQB: PROBF) (“Probe” or the “Company”) is pleased to announce the release of an Updated Resource Estimate for its Monique property (the “Property”), part of the Novador Project (formerly Val-d’Or East) located near Val-d’Or, Quebec. The mineral resource has shown significant improvement over the previous resource estimate and remains open for future expansion. The new resource at Monique stands at 2,038,900 ounces of gold within the indicated category and 357,200 ounces of gold within the inferred category, demonstrating a global increase of the overall project and excellent conversion rate from Inferred to Indicated. In addition to the substantial increase at Monique, the updated resource was also successful in converting an additional l,367,000 ounces to the indicated category from the 2021 resource estimate, more than tripling the Indicated resources for Monique. The Monique resource estimate was independently prepared by InnovExplo Inc. in accordance with National Instrument 43-101 (“NI 43-101”) and is dated January 16, 2023. This estimate includes the resource from the Monique property only and the resource updates on the Pascalis and Courvan trend deposits will follow later in Spring 2023 and are expected to show significant improvement in the indicated resource and a potential increase in the total gold inventory for the three combined deposits. Drills will be active throughout 2023 on further expansion and regional exploration with a significant drilling program totalling 50,000 metres at Novador (previously Val-d’Or East).
David Palmer, President and CEO of Probe, states, “Once again Monique has exceeded our expectations showing a significant increase in gold resources of more than a million ounces and more than tripling the amount of Indicated resource. With a 2.4 million ounces inventory now hosted by Monique, and 5.1 million ounces expected in total inventory, our expansion and conversion programs were highly successful and confirmed the consistency, and quality, of the Monique deposit. In addition, we also saw an increase in grade of the pit-constrained resources, reflecting the better-than-expected drill results throughout the year. The current Resource Update also demonstrates the potential for continued growth at Monique. Given the success of our drilling programs, we have commenced our 2023 expansion drilling program at Monique with four drills currently turning on the property. This, in addition to our large generative exploration drilling programs at Novador and Detour, we will continue to successfully advance our projects throughout 2023”.
Yves Dessureault, COO of Probe, states, “This resource estimate is the culmination of the 2022 work programs at Monique from a dedicated team of employees and partners who have worked very hard to bring us this fantastic result. The quality of the resources has improved significantly and the excellent conversion rate from Inferred to Indicated is a testament to the quality of our geological model. The gold resources at Monique are now combined into a single expanded pit, compared to the 3 pits in the 2021 Resource, potentially enhancing the future mine plan and enabling us to consider the use of a smaller fleet with larger equipment. Given the increase in gold resources, we will now be performing trade-off studies to review, and potentially increase, the plant throughput and production profile from the currently contemplated 207,000 ounces average annual gold production. We continue to believe that the ore sorting technology has a role to play in our project with the potential to bring significant sustainable development benefits. As with the 2021 Resource, the additional ounces that could potentially be extracted from mineralized waste using this technology are presented in a separate table, which shows the potential for an additional 166,900 ounces in the Indicated resource and 56,500 in the Inferred resource categories that could be added to our gold inventory within Monique."

Notes:
The Company has demonstrated with a series of performance tests that the industrial sorting technology works very well with the type of mineralization found on the Novador project. By applying industrial sorting to mineralized waste with very conservative gold recoveries, additional mineral material can be extracted from the mineralized waste and thus become additional mineral resource on the Project.

Resource Estimation Methodology and Parameters
As part of the resource estimation process, the Company and InnovExplo compiled, verified, and modelled all technical information available from the Project, including 960 drill hole collars consisting of 124,181 gold assays, which represented 239,553 metres of drilling. 3D geological models were built for sub-vertical structures and included key structures hosting and constraining gold mineralization along the Monique Gold Trend. The drill holes database closing date is October 25th, 2022.
Novador Project – Other Estimates from Courvan and Pascalis Gold Deposits
In addition to the new Monique mineral resources (this Press Release), the Novador Project also includes the Courvan Trend and Pascalis Trend gold deposits.
The result from historical mineral resources estimates on Courvan, Pascalis and other smaller deposits on the Project were published previously by the Company and are available in “NI 43-101 Technical Report for the Val-d’Or East Project, Abitibi Greenstone Belt, Quebec, Canada”. The Report dated July 14th, 2021, was prepared in accordance with National Instrument 43-101 (“NI 43-101”) is available for review on both SEDAR (www.sedar.com) and the Company’s website (www.probemetals.com).Those mineral resources estimates were completed following NI 43-101 and CIM definitions standards and guidelines and were addressed to the Company. Those deposits have been significantly drilled (390 holes totaling 76,839 metres) since their estimations and the 2021 mineral resources estimates are not considered current but “historical” at this stage. The Company is currently in the process of compiling results and updating the mineral resources of these two additional gold deposits considering their potential synergy with Monique as demonstrated in the 2021 PEA ("Val-d’Or East Project, NI 43-101 Technical Report & Preliminary Economic Analysis” dated October 20, 2021). For illustrative purposes, those latest “historical” estimates for the Pascalis and Courvan deposits, independently prepared in 2021 by Merouane Rachidi, Ph.D. P.Geo. and Claude Duplessis, Eng. from GoldMinds Geoservices Inc. are presented in table 5.

About Novador Project
Since 2016, Probe Gold has been consolidating its land position in the highly prospective Val-d’Or East area in the province of Quebec with a district-scale land package of 436 square kilometers that represents one of the largest land holdings in the Val-d’Or mining camp. The Novador project is a sub-set of properties totaling 175 square kilometers hosting three past producing mines (Beliveau Mine, Bussière Mine and Monique Mine) and falls along three regional mine trends. Novador is situated in a politically stable and low-cost mining environment that hosts numerous active producers and mills. The Monique property, part of the Company’s Novador Project, consists of 21 claims and one mining lease, covering a large portion of the reported gold resource, with a total area of 5.5 square kilometres in Louvicourt township, located 25 kilometers east of Val-d’Or.
Monique Property Geology:
Gold mineralization on the Monique property is mainly associated with three deformation zones that cross the property with an orientation of 280° and a 75°- 80° dip to the north. Gold mineralization is defined by a network of quartz/carbonate/albite/±tourmaline veins and veinlets with disseminated pyrite in the altered wall rocks. More than thirty-eight (38) parallel gold zones have been discovered on the property, to-date. Some mineralized zones have been defined from surface to a depth of 700 metres and vary in width from 1 metre to up to 100 metres. Mineralized structures extend laterally up to 1,500 metres.

During the 2021 and 2022 drilling program, assay samples were taken from the NQ core and sawed in half, with one-half sent to Activation Laboratories Ltd. or AGAT Laboratories Ltd. and the other half retained for future reference. A strict QA/QC program was applied to all samples, which includes insertion of mineralized standards and blank samples for each batch of 20 samples. The gold analyses were completed by fire-assayed with an atomic absorption finish on 50 grams of materials. Repeats were carried out by fire-assay followed by gravimetric testing on each sample containing 3.0 g/t gold or more. Total gold analyses (Metallic Sieve) were carried out on the samples which presented a great variation of their gold contents or the presence of visible gold. Historical drilling program assay sampling procedures are disclosed in the NI 43-101 technical report: Mineral Resource Val-d’Or East Project – July 14, 2021, and available on SEDAR (www.sedar.com) under Company's issuer profile.
