VANCOUVER, British Columbia, April 16, 2026 (GLOBE NEWSWIRE) — Precore Gold Corp. (CSE: PRCG) (the “Company” or “Precore Gold”) is pleased to announce the completion of a data compilation program at its 100 %-owned Lac Big-Rush Gold Property (the “Property”) in the prolific Chibougamau mining camp, in Quebec.
After several weeks of reviewing and compiling historical data from past exploration work undertaken on the property prior to the 1980’s, as well as incorporating important data gained through Quebec’s Ministère des Ressources Naturelles et des Forêts databases, Precore Gold is looking forward to using cutting-edge, verified and proven Artificial Intelligence (“AI”) technology, provided by Windfall Geotek Inc. The objective is to add a second layer of interpretation and to outline high-priority drill targets across Lac Big-Rush’s 2,712 hectares, located adjacent to Iamgold’s Nelligan Complex, and a mere 300 meters from their Croteau Deposit (Inferred near surface resource of 640,000 oz at 1.73 g/t). This AI work will also enable Precore to minimise time spent doing traditional field work at Lac Big-Rush during its maiden exploration campaign, later this year.

Paul A. Dumas, Precore Gold Executive Chairman explains, “We are very excited to be working on our Lac Big-Rush project, which hasn’t had any exploration work done on it since the early 1980’s. Lac Big-Rush presents Precore with great optionality vis-à-vis our flagship Arikepay project in Peru, giving us a second project with great gold discovery potential in a Tier-1, mining friendly jurisdiction. We also look forward to working with the team at Windfall Geotek and their use of cutting-edge technology to define priority drill targets at Lac Big-Rush. They have had quite an impressive track record of successes elsewhere, so I am looking forward to their interpretation at Lac Big-Rush.”
About the Lac Big-Rush Property
The property geology is characterised by basalt, amphibolite interlayered with gabbro sills of the Bruneau Formation (see Figure 3). The property is located along the east-west Faribault and Croteau inverse faults and shears, and is included in a gold bearing area, neighboring to the west of Iamgold’s Croteau Project (see Figure 2).
According to public records, about 20 diamond drill holes (“DDH”) were drilled on the property between early 1950’s and 1986, including 10 DDH by Noranda Inc. Two historical and noteworthy gold showings, namely Tadd and Croteau West, are listed in the Province’s Sigeom database (Figure 1 & 4).
The Tadd showing is interpreted as a 2.3 meters wide mineralized quartz vein on average, followed over 50 meters of strike length. Two grab samples returned 7.33 grams per tonne (“g/t”) Au and 5.33 g/t Au respectively (Sigeom).
The Croteau West showing located about 2.5km east of the Tadd showing is an outcropping mineralized occurrence. A grab sample returned 65.15 g/t Au and a channel sample returned 3 g/t Au over 1.5 meters during Cree Mineral Exploration Board 2018 prospecting program (assessment report GM-71214).

All statements, other than of historical facts, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future including, without limitation, the completion of the Second Tranche, future geological work or exploration programs, the potential positive exploration results, the timing of the exploration results, the ability of the Company to finance exploration programs and the potential mineralization or potential mineral resources are forward-looking statements. Forward-looking statements are generally identifiable by use of the words “will”, “should”, “continue”, “expect”, “anticipate”, “estimate”, “believe”, “intend”, “to earn”, “to have”, “plan” or “project” or the negative of these words or other variations on these words or comparable terminology.
