Updated Open Pit

Stamford Bridge

During Q1 2025, the Company announced its best drill results ever, on a gtm basis with hole BMDD315 intersecting 37 m @ 6.86 g/t Au (253.82 gtm) from 130 m. This drill hole result is approximately 250 m east of the Buckreef Main Zone, host to Buckreef Gold’s 2M+ ounce Au Mineral Resource1 and where current operations are ongoing in the Main Pit. This drill hole result comes following the previous best drill result, with hole BMDD310 intersecting 35.5 m @ 5.48 g/t Au (194.54 gtm) from 64 m. This drill hole result is approximately 200 m east of the Buckreef Main Zone.

The Company also announced the discovery of a promising new gold mineralization shear zone, named the “Stamford Bridge Zone” at which current drill results are revealing geological characteristics and mineral alterations similar to that at Buckreef’s Main Zone. Holes BMDD315 and BMDD310, mentioned above, are located along the Stamford Bridge Zone.

Stamford Bridge Shear Zone Highlights:

  1. Hole BMDD315 intersected 37 m @ 6.86 g/t Au from 130 m; including 23 m @ 9.31 g/t Au from 139 m.
  2. Hole BMDD310 intersected 35.5 m @ 5.48 g/t Au from 64 m; including 13m @8.06g/t Au.
  3. Hole BMDD312 intersected 17.2 m @ 3.14 g/t Au from 164.6 m.
  4. Geotechnical hole BMGT001 intersected 11.39 m @ 2.80 g/t Au from 104.0 m, and 22.0 m @ 2.36 g/t Au from 186.6 m. Both results are interpreted to be part of the Stamford Bridge Zone trend.
  5. BMGT001 intersected the Buckreef Main Zone of 32.80 m @ 1.70 g/t Au (ending in mineralization) from 393.0 m.

During Q2 2025, the Company announced three additional drill hole results (BMDD319-321) providing further evidence of gold mineralization along the Stamford Bridge Zone as follows:

  1. Hole BMDD319 intersected 21.0 m @ 8.63 g/t Au from 81.0 m.
  2. Hole BMDD320 intersected 20.5 m @ 5.14 g/t Au from 125.5 m.
  3. Hole BMDD321 intersected 5.0 m @ 2.74 g/t Au from 157.0 m.

The Stamford Bridge Zone was discovered through detailed geological mapping of the Main Pit floor that identified a trend of high-grade mineralization on the eastern side of the Main Pit trending 070 East (Figure 1). This is an exceptional discovery at the Buckreef Gold Project, resulting in the most significant mineralization identified within Buckreef Gold’s drill history.

The exploration team then identified that geotechnical hole BMGT001 (one of geotechnical holes drilled as part of the Buckreef Main Zone geotechnical study completed by Terrane Geoscience Inc.) located 160 m east of the Main Pit, drilled across the Stamford Bridge (Figure 1), and was subsequently relogged (Table 1). The logging confirmed the presence of three mineralization zones, including the Stamford Bridge Zone. The zones were sampled, and the assay results are summarized below (Table 1). To date, the new Stamford Bridge Zone has shown evidence of a sheared mineralized zone with similar geological characteristics to that found in the Main Zone, i.e., zones are measured as being near vertical with strong alteration.

Thus far, drilling has covered more than 150 m of this newly identified mineralized structure and geological logging confirms the continuity of the structure. These results are beginning to form what can become a potential 1-kilometer “bridge” between the Buckreef Gold Main Zone, where current operations are ongoing, and the parallel, high-priority, gold mineralization zone known as the Eastern Porphyry (see Figure 1). The latter also links to the Anfield Zone to the southeast, discovered in 2022.

The Company has planned an expanded diamond drill program to test for further mineralization along this newly developing trend.  Although these are early-stage results, and only two sections along the newly identified trend have been drilled, key interpretations include:

  1. The Stamford Bridge Zone is potentially a significant shear zone and geologically similar to the Buckreef Main Zone. It bridges the gap between Buckreef Main Zone and the Eastern Porphyry deposit to the Southeast.
  2. Pinching and swelling of the Stamford Bridge Zone has been observed in the first section drilled; 4m wide in the first drillhole and over 17 m wide on the second drillhole down dip; and
  3. The second section has intercepted a significant shear zone, over 35 m wide with distorted shear fabric by alteration overprint. Therefore, a minimal number of follow-up drillholes will be required to understand geometry of this new discovery.
