QUANTUM SECURES CLAIM COVERING HISTORIC SILVER WORKINGS AT BABINE SOUTH, BRITISH COLUMBIA

Further to the news of Jan. 14, 2026, Quantum Critical Metals Corp. has expanded its mineral tenure at the Babine South silver project to include a neighbouring adit known as East Sunrise with notable historical silver values.

The newly acquired claim is contiguous to the existing Babine South property, covering the Boling showing, which reports favourable host rocks and historical silver mineralization recorded in B.C. Minfile 093K 028, including grab samples assaying up to 835 ounces per ton silver (26,000 grams per tonne Ag), chip samples assaying 1.1 oz/t silver (34.2 g/t Ag) and float returning 417 oz/t silver (13,000 g/t Ag).

The expanded Babine South silver claim group covers 1,108 hectares, strengthening Quantum's control over a prospective silver-bearing structural corridor defined by multiple historic workings, surface exposures, favourable host lithologies and recent geological interpretation from site visits in 2025.

"We view this land expansion as a strategic step that brings historically documented compelling silver occurrences under unified ownership," said Marcy Kiesman, chief executive officer of Quantum Critical Metals. "The historical data demonstrates repeated silver mineralization across multiple workings, time periods and locations. Our objective now is to systematically evaluate this system using modern exploration methods to better understand its continuity, scale and controls."

About Babine South: a silver system with limited exploration

Silver mineralization at Babine South was first discovered in the 1920s, when it was reported that 94 kilograms of silver was produced from a trench. Two adits (East and West) were driven to intersect the mineralization, and, in 1991, an area near the East adit known as the Silver Pit was reopened to confirm the presence of native silver, which was confirmed by a rock sample assaying 835 oz/t silver (26,000 g/t Ag), B.C. assessment report No. 22157.

The Babine South property covers five mineral claims and is approximately 1,108 hectares. The geology of the Babine South project area includes phyllite, marble, and dioritic and monzonitic volcanic and igneous rocks. Four phases of veining run through the area and are crosscutting. The project is thought to be epithermal; however, historically, there was some association of the veining with the foliation and shear zones. Mineralization includes quartz-carbonate veins including native silver, galena, sphalerite, tetrahedrite, argentite and chalcopyrite (polymetallic silver, lead, zinc and copper), B.C. assessment report No. 22157.

East Sunrise adit: structural continuity and grade confirmation

The newly secured East Sunrise adit extends approximately 56 metres and was driven to intersect a narrow quartz-carbonate vein hosting silver-rich galena. The East adit is located approximately one kilometre east of the West adit, potentially suggesting lateral continuity within a broader mineralized system.

Historical float and grab samples collected from an open cut approximately 20 metres above the East adit portal returned assays of up to:

• 13,000 g/t silver (417 oz/t Ag);
• 42.8 g/t gold;
• 6.39 per cent lead.

These results, recorded in assessment report 15358, indicate a polymetallic (silver, gold and lead) epithermal vein system with both precious and base metal components, and confirm that high-grade silver mineralization is present at surface and in underground exposures.

Planned exploration and next steps

Planned work at Babine South will focus on advancing the project from historical documentation toward drill-ready targets and includes:

• Detailed geological and structural mapping to refine vein orientations and controls;
• Targeted surface sampling to confirm grade distribution and mineral associations;
• Induced polarization geophysical surveying to test for subsurface continuity beneath historic workings and along strike.

These programs are expected to refine the existing geophysical and geochemical anomalies and help further delineate priority drill targets for the 2026 exploration season.
