Evrim Resources has announced that a drilling program has commenced at the Cerro Cascaron gold and silver project in southwestern Chihuahua, Mexico.

Evrim and exploration partner, Harvest Gold, have planned up to 3,000 metres of diamond drilling.
“Cerro Cascaron is a large underexplored and undrilled project with two known areas of veining with outcropping gold and silver mineralization, including bonanza grab samples of up to 1,670 g/t gold and 1,490 g/t silver,” commented Stewart Harris, Vice President of Technical Services. “This maiden drill program will initially test a zone of sub-parallel veins at the Cascarita silver target followed by drilling within four vein targets in the Cascaron vein field.”
In addition to the drill program, Evrim and Harvest Gold will contribute to various community initiatives including the improvement of road access to local farms following the recent wet season, clearing a local airstrip to allow for scheduled flight services, and continuing to support the legal organization of nearby Ejido groups.
Cascarita Silver Target
The drill program will commence at the Cascarita silver target where three drill holes are planned to test over 350 metres of strike length, along a 900 metre polymetallic silver-lead-zinc sheeted vein/breccia system. The initial drill targets are defined by underground channel and surface grab samples undertaken by Evrim in 2017 that returned five channel sample cuts with widths between 1.4 metres to 3.3 metres grading between 231 g/t silver equivalent and 542 g/t silver equivalent.
Cascaron Vein Field Targets
Four drill holes from one site are planned to test the San Pedro vein, where high grade gold and silver veins are defined by channel sampling, and by gold, silver, and pathfinder soil geochemistry approximately 800 metres to the north. Channel sample results collected from the San Pedro vein returned sample grades of 19 g/t gold and 72.6 g/t silver over 0.8 metres within 2.6 metres grading 6.05 g/t gold and 28.3 g/t silver.
Approximately 45 metres further north, channel sampling returned grades of 10.5 g/t gold and 46.4 g/t silver over 0.9 metres within 4.3 metres grading 2.22 g/t gold and 10.9 g/t silver.
Three drill holes are planned to test 900 metres of strike along the Serpiente Dorada and Julieta structures, an area within a 1.8 kilometre long gold-silver soil anomaly that averages above 50 ppb gold with the peak being 1.38 g/t gold. The drill holes will test an area of high-grade gold-silver mineralization defined by channel and grab samples at Serpiente Dorada, and strong geochemical anomalies defined by the Julieta structure and the Julieta-Serpiente structural intersection.
Previous selected hand grab sampling of Serpiente Dorada returned gold grades from trace to 1,670 g/t gold and 1,490 g/t silver, while channel samples collected with a rock saw on the Julieta vein returned sample grades of 5.04 g/t gold and 14.4 g/t silver over 2.0 metres within 6.3 metres grading 2.16 g/t gold and 28.8 g/t silver.
Epithermal veins commonly transition from multiple narrow veinlets in the brittle rhyolite and rhyolite tuffs into a single broader vein in more component andesite units beneath. The drilling at Serpiente Dorada will test this concept at Cerro Cascaron.
The Carabina vein area will see diamond drill testing with one drill hole planned beneath an area of high grade gold-silver surface samples. In 2016, channel sampling across the Carabina vein returned sample grades of 5.73 g/t gold and 29.3 g/t silver over 1.4 metres within 5.4 metres that graded 2.12 g/t gold and 14.5 g/t silver.
