Norsemont Mining Inc. announced the third tranche of results from its 2021 maiden diamond drilling program at the company's Choquelimpie high sulphidation epithermal gold-silver project in northern Chile. MV21-009 was sited to test for extensions of mineralisation to the south-east and beneath the Choque Pit,. The hole intersected grey silica matrix hydrothermal breccias with pyrophyllite-dickite advanced argillic alteration and disseminated and crackle-hosted pyrite (±enargite-sphalerite) mineralisation.

Notable mineralised intervals include 15.0 m of near surface oxide gold followed by 170.0 m of highly significant gold-silver mineralisation. Drillhole MV21-001 was planned to test for extensions of the hydrothermal breccias seen in the Vizcachas pit to the north and to depth. The hole cut a multi-pulse breccia complex made up of chaotic matrix, tuffisite matrix and hydrothermal matrix breccias with advanced argillic alteration (dickite-pyrophyllite, illite-pyrophyllite) and silicification thought to represent the transition from the upper epithermal environment to the deeper porphyry environment.

Mineralisation occurs as sulphides of pyrite (± enargite-galena-sphalerite) with gold grades open in all directions. MV21-007 was sited to extend mineralisation between the Intermedio pit and the open mineralisation intercepted in historic drillhole R144 (69m @ 2.76 g/t Au, 21.9 g/t Ag). The hole cut a daci-andesite dome with argillic and advanced argillic alteration.

Oxide mineralisation extends to 18.7 m before entering the sulphide zone with pyrite (±sphalerite-galena). The alteration and mineralisation, which returned sporadic intercepts, is interpreted as being typical of the peripheral “halo” to the high-grade zones seen in the Intermedio Pit.
