Minaurum Gold Inc. provided an update on the underground rehabilitation work at the historical Promontorio mine, located in its flagship 100%-owned Alamos silver project in Sonora, Mexico. Minaurum has successfully accessed and is dewatering the main haulage level along with clearing crosscuts in the El Tirito area of the mine. This led to the discovery of several historical underground drill collars, confirming historical reports from the 1960s.

Five service holes were drilled to provide air, water, and electricity to facilitate underground rehabilitation efforts. Three of the service holes intercepted the Promontorio vein at its highest levels returning high-grade base metal mineralization including 5.8 m of 98 g/t Ag, 3.6% Pb, and 7.9% Zn. Sampling and mapping of dumps at Promontorio revealed a boulder of massive sulfide vein assaying 3,320 g/t Ag, 54.7 g/t Au, 25% Cu, 6.5% Pb, and 1.1% Zn.

The boulder, measuring roughly a meter across, is an indication of the type of grades exploited by early miners at Promontorio. The workings are in good condition. Rehabilitation and exploration work efforts are focusing first in the El Tirito shaft area, which lies approximately 300 m from the Promontorio adit entrance.

Crews are clearing and stabilizing cross cuts and stopes, including access to the internal shaft. Activities completed include timbering and shoring up the adit entrance, preparing a staging area outside the adit entrance, cleaning out and stabilizing the adit, and draining water from the main haulage level. Approximately 200 tonnes of ballast and 50 tonnes of backfill have been removed from the first 300 m of the haulage level and stockpiled outside the mine entrance.

Sampling results will be released shortly. Drill steel marking the collar locations of three historical holes (U-7, U-8, and U-9) was located approximately 250 m into the main haulage level, confirming historical data. Two of the holes returned 2.7 m of 274 g/t silver (Hole U-7, approximately 30 m below haulage level), and 2.1 m of 247 g/t silver (Hole U-8, approximately 50 m below haulage level).

No assay information is available for Hole U-9. The relationship of the reported intercept of Hole U-7 to the historical drilling and workings, as well as to Minaurum's drilling, confirm the general model of a NNE-trending, steeply WNW-dipping vein zone. Hole U-8's intercept appears to confirm mineralization in a NW- trending fault. Based on both sets of drill holes, potential for high-grade silver mineralization at depth at the lower levels, and on the southwest side, down-dropped side of the northwest-trending fault exists.

Five service holes were drilled to provide electricity and air to the underground workings. Two of the service holes were in the El Tirito area and three were drilled in the Balvanera area. The three parallel service holes drilled at the Balvanera area are separated by less than 2 metres.

Each drilled a high-level mineralized vein/fault zone from approximately 93 to 99 m. Mineralized intercepts in the service holes confirm the continuity of the vein zone and variability of grade and thickness along it; intersecting high-grade base metals of 7.9% zinc, 3.6% lead, 0.34% copper and 0.48 g/t gold (Hole AL22-100) and 5.5% zinc, 3.1% lead, and 0.24% copper (Hole AL22-101).
