MANTARO PRECIOUS METALS CORP. reported complete results from the 21 diamond core holes drilled by the Company in 2022 at the Golden Hill property in Bolivia (‘Golden Hill'). Additional drilling is required to determine true widths as all holes intercepted veins at an oblique angle.

The assays are not capped. Broad gold mineralization was intercepted across the 'GC' structure in the northern most and southern most holes at the Gabby prospect (holes GH0018 and GH0019 respectively). Holes GH0015, GH0016 and GH0017 were drilled to test the down dip extensions of quartz shear zones mapped at surface across the central Gabby area.

These structures were intercepted at depth in all holes, however gold grades were of low tenor with no significant gold values intercepted. The Company has taken thin section samples of these barren quartz shear zones to better understand the gold deportment within the Gabby system, which will assist in guiding future drilling. About the Golden Hill Property: Golden Hill is centered on a broadly north-south trending regional structure that hosts the La Escarcha underground mine and the Gabby, Garrapatillia and Brownfields workings and gold-bearing vein occurrences in its western hanging wall.

The same structure hosts numerous saprolite gold and hard rock gold deposits to the north and south of Golden Hill over a strike length of at least 25 kilometers - underpinning the significant control the structure exerts on gold mineralization. A northwest-trending splay of this structure hosts areas of alluvial and saprolitic/hard rock workings within Golden Hill and immediately to the north. At least six strike kilometers of these structures are known within Golden Hill in addition to the four kilometers between La Escarcha and Brownfields which have been mapped in detail.

Known mineralization and surface anomalism is open along strike on all structures. Mineralization between La Escarcha and Brownfields is characterized by a series of broadly parallel, north-south trending, very steeply dipping quartz veins that are between 1 to 5 meters wide. Mineralization is hosted in mafic metavolcanics, at the contact of metavolcanics and metasediments, and within metasediments.

Veins are well exposed in underground workings at La Escarcha where they comprise multiphase white quartz and slivers of wall rock which are fracture oxidized. Veins are up to 5 meters wide and contain significant visible gold. Most gold appears to be free hosted in fractures within quartz and pyrite.
