VAL-D'OR, QC, July 9, 2026 /CNW/ - SOQUEM, a subsidiary of Investissement Québec, is pleased to announce the results of its winter 2026 drilling program on the Lespérance-Lac Shortt Project (the "Project"). The wholly owned project is located in the Eeyou Istchee James Bay territory (Desmaraisville area) in Québec, Canada.
Highlights from the Boyvinet area:
The Project is located in the Abitibi Subprovince, at the junction of two regional deformation corridors -- Opawica-Guercheville (Nelligan and Philibert deposits) and Wedding-Lamarc -- which are important metallotects for gold mineralization in the area. Near the project are the former mines of Lac Shortt (historical production of 400,000 ounces of gold, DV 2010-01) and Bachelor (historical production of 350,000 ounces of gold, SLR 2021) (Figure 1).
The exploration program completed in February 2026 (21 holes; 4,473 m) aimed to determine the geometry and continuity of the Boyvinet and Boyvinet-Ouest zones (press release dated October 14, 2025) (Figure 2).
Boyvinet area
The eleven (11) holes drilled in the Boyvinet area, totalling 2,904 m, revealed at least four (4) gold-bearing zones lying parallel to the Lac Shortt Deformation Corridor, with east-west trends and moderate dips to the north. These anastomosing gold-bearing zones lie within a corridor approximately 400 m wide, which was traced for nearly 1.6 km and remains open in all directions (Figure 3).
The best results are:
The mineralized corridor follows the contact between the mafic units of the Filon-couche d'Esturgeon and the Formation d'Obatogamau to the north and the Stock de Boyvinet to the south. The documented gold-bearing zones are mainly found within the Stock de Boyvinet, a monzodioritic intrusion of calc-alkaline affinity. They occur as intervals containing up to 5% very finely disseminated pyrite associated with wide (metric to pluridecametric) zones of intense and pervasive alteration to hematite, albite, silica, carbonate and sericite (Figure 4), most often demagnetized. The geochemical signature of the mineralized intervals indicates a dominant Au-As-S association, and to a lesser extent Cu-Co-Ni. These observations are consistent with a combination of characteristics specific to the metallogenic models of intrusion-related gold systems (IRGS) and orogenic deposits.
Boyvinet-Ouest area
The objective of the eight (8) drill holes (1,239 m) in this area was to test the continuity of the gold-bearing deformation zone (315°N trend, 35° dip) uncovered during the previous drilling program. Six holes intersected the zone, which is now closed to the northwest but remains open to the southeast, where hole 1435-26-54 returned an interval of 0.55 g/t Au over 3.7 m.
Next steps
SOQUEM plans to conduct a drilling program in the winter of 2027 to continue exploring the Boyvinet gold corridor.
The work will focus on the area's potential for low-grade, high-tonnage mineralization, including shallow targets at the western end where the best results from the last program were obtained, as well as the nearer-surface zones further south in the corridor.

About Lespérance-Lac Shortt
The Lespérance-Lac Shortt Project comprises 192 mining claims (100.73 km2). This flagship project is situated on the territory of the Cree Nation of Waswanipi, and access is via regional highway 113, which links Val-d'Or to Chibougamau.
Analytical Protocols
Strict QA/QC protocols were implemented, including the insertion of certified reference material and blanks. All samples were sent to Activation Laboratories Ltd. (Actlabs) in Val-d'Or for preparation and analysis.
Samples were weighed, crushed, pulverized, dissolved using the 4-acid method, and analyzed by ICP-MS/OES for 48 elements. For Cu, Zn and Pb grades exceeding 1%, the sample was re-assayed by 4-acid digestion followed by ICP-OES analysis.
For gold (Au), 50 g of material was analyzed by fire assay with atomic absorption spectrometry (AAS) finish. Samples grading over 5.0 g/t Au were systematically re-assayed by gravimetry using pulp material.
