Kingston Resources Limited has produced an update Mineral Resource Estimate (MRE) for the Southern Ore Zone (SOZ) at the Mineral Hill Mine. This is a major advancement for the company and marks the first update of Mineral Resources since the asset was acquired in January 2022. This type of work at Mineral Hill is continuing to reveal the potential value that can be created from modern and thorough technical work.

Total Resources have increased substantially compared to the May 2016 estimation, with 114% increase in total tonnage, 54% in contained gold and 64% contained copper. Contained silver, lead and zinc have also increased by 131%, 175% and 193% respectively. Key updates in the current MRE include refined geology interpretations and the use of a $50/t net smelter return reporting cutoff.

The previous MRE for SOZ used a 1.5% CuEq reporting cutoff. The updated metrics proved a better reflection of the reasonable prospects for economic extraction given the current critical minerals landscape. The location of SOZ in relation to the surface infrastructure at Mineral Hill.

Mining was historically undertaken using underground drive development and long-hole stoping. The mineralisation at SOZ comprises an epithermal polymetallic vein and breccia system hosted within the Late Silurian to Early Devonian Mineral Hill Volcanics. The mineralised breccias are sub-parallel and en-echelon, generally dipping 65° to the west at over 500m of strike.

Mineralisation currently extends from 150m to 300m depth below surface. The deposit is open at depth and along strike. Lodes identified as A (most eastern), B and C commonly occur as breccias, composed of volcanic wall rock and older quartz-sulphide vein fragments set in a silica and sulphide matrix and locally containing massive sulphide.

Lodes D, G and H are dominantly copper-gold bearing and lead-zinc poor. Shows an oblique section with the interpreted lodes and existing underground development. Recent drilling highlights at SOZ include: 39m @ 1.1% Cu, 0.7% Pb, 0.8% Zn, 0.93g/t Au, 12g/t Ag from 161m; and 9.8m @ 4.22g/t Au, 0.7% Cu, 3.2% Pb, 3.2% Zn, 30g/t Ag from 166m1.

Kingston is targeting the re-establishment of mining at SOZ underground, leveraging the existing decline development and infrastructure for a low-cost restart.
