PRISMO METALS BRINGS AI TO HOT BRECCIA COPPER PROJECT IN ARIZONA

Prismo Metals Inc. has hired Exploration Technologies Inc. (ExploreTech) from San Diego, Calif., to apply xFlare, its artificial intelligence-optimized drill planning solution, to its Hot Breccia project where a number of features suggests well-mineralized Arizona-style copper porphyry lies at depth.

The xFlare AI approach is specifically designed to combine surface geology and drilling results with computationally intensive remodelling of existing geophysical datasets to optimize targeting of covered targets. The process quickly generates thousands of solutions that cluster on the best fits between the geological and geophysical data and then generates drill hole trajectories designed to cut those clusters most effectively.

Dr. Craig Gibson, president and chief executive officer of Prismo Metals, commented: "The Hot Breccia project should be an ideal place to apply xFlare. It lies in the world-famous Arizona copper belt, between several very well understood world-class copper mines including Morenci, Ray and Resolution. Hot Breccia shows many features in common with these neighbouring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth. Prismo ran a ZTEM survey last year that identified a very large conductive anomaly directly beneath the breccia outcrops and expects xFlare's AI approach to zero in on where and at what depth to drill. The drill permitting process is well advanced."

"Hot Breccia has all the right elements for significant porphyry copper and skarn mineralization, and we are thrilled to be partnering with Prismo to optimize their drilling," said Dr. Alex Miltenberger, ExploreTech's co-founder and chief executive officer. "Prismo's ZTEM anomaly is very strong and xFlare was designed precisely to refine these kinds of data to match what is known of the geology and the target model."

The ZTEM survey identified a large conductive body at depth below the surface exposure of a large dike swarm that hosts the namesake breccias. Anomalous copper and gold assays are locally present at the surface in this area (see press release of July 11, 2023), and high-grade copper and zinc assays are present above this anomaly in historic drill holes completed by major copper producers in the 1970s and early 1980s (see press release of Jan. 29, 2023).

While all of the historic drill holes intersected hydrothermal alteration within the volcanic rocks that overlie the typically better mineralized Paleozoic carbonate rocks with increasing alteration intensity downwards, no historic drilling targeted this newly identified conductive zone identified in Prismo's ZTEM survey. The carbonate host units above the anomaly have several copper intercepts reported to exceed 1 per cent copper and elevated zinc levels.

Assay results from historic drill holes are unverified as the core has been destroyed, but information has been gathered from memos, photos and drill logs that contain some, but not all, of the assay results and descriptions.
