First Phase Drill Program At La Plata Copper-Silver-Gold-PGE Project

VANCOUVER - Metallic Minerals Corp. reported the start of the 2023 exploration and drill campaign at the La Plata copper-silver-gold-PGE project, located in southwest Colorado. In May 2023, Newcrest Mining Limited completed a 9.5% strategic equity investment into Metallic Minerals with the goal of accelerating advancement of the La Plata porphyry project. This funding will support a two-phase drill campaign in 2023 that will build on the success from work in 2022. The initial phase is expected to consist of approximately 5,000 meters of diamond core drilling, primarily focused on resource expansion at the Allard porphyry deposit.

A top priority for the program will be to conduct step-out drilling from the major discovery in drill hole 22-04 which intersected 816 meters of 0.41% Cu Eq (0.30% Cu, 2.47 g/t Ag, 0.038 g/t Au, 0.055 g/t Pd and 0.093 g/t Pd) from surface and ended in 5.39% CuEq over 5.2 m (2.44% Cu, 18.7 g/t Ag, 5.0 g/t Au+PGE). Hole 22-04 did not reach target depth and ended in mineralization due to mechanical issues. Drilling in 2023 will test the lower limits of mineralization and some holes are scheduled for as deep as 1,200 meters.

Scott Petsel, President, stated, "We see a real opportunity for world class scale and grade at La Plata and have confidence in our ability to quickly grow the existing resources. Hole 22-04 was not only the widest and highest-grade drill hole ever drilled on the project, it was also one of the top holes drilled in the last several years at any copper project in North America. We also expect to be able to increase the overall grade of the resource moving forward as we include precious metals credits previously not accounted for. Our exploration work over the past two years has defined 16 additional untested porphyry targets across the greater property, which appear to have very similar characteristics to the Allard deposit and could result in additional new discoveries. The drill is currently mobilizing to site."
