In October 2025, we expanded our successful deep, step-out drill program at the O’Brien Gold Project to what will be an eventual 140,000 metres with up to eight drill rigs. The drill program is ongoing, and in March of this year we demonstrated its value with an interim, and meaningful, increase in the estimate of the Project’s mineral resources. With this financing completed, we can now (i) plan the expansion and extension of our drilling through to the end of 2027, (ii) manage our capital resources more efficiently with our “flow-through” eligible exploration expenditures, and (iii) establish a strong treasury to support project development activities and project de-risking. In particular, our step-out drilling ambition is to go deeper. Until now, our exploration horizon has been to a floor of 2 kilometers depth. Results to date indicate extensive gold mineralization with good continuity beneath the former mine and the current mineral resources to at least 1.9 kilometers depth (see Radisson news release dated April 30, 2026). Given the character of neighboring gold deposits and the wealth of mining infrastructure within or close to the O’Brien Gold Project, we now intend to extend our exploration to a depth of 2.5 kilometers with new deep drilling and directional wedging. We believe that O’Brien gold mineralization has the potential to extend to at least these depths, that such mineralization offers the potential for significant new mineral resources in excess of our current exploration target, and that these mineral resources might be reasonably expected to be developed.”
