Exploration Results From The Sarape Project

VANCOUVER - Evrim Resources Corp. reported drill results from the 2019 maiden drilling program at the Sarape project in Sonora, Mexico. At the completion of the program, the Company’s exploration partner, a subsidiary of Coeur Mining, Inc., relinquished their option on the project.

“Evrim and Coeur completed a ten hole maiden drill program at the Sarape project testing for blind mineralization along the Sarape, La Nube, and Chiltepin veins. The drill program intersected a fissure vein up to 23.6 meters wide on the Sarape vein with consistent low-level gold and silver values. To date, only 380 meters of the six kilometer strike length of the Sarape vein has been tested.”, commented Evrim VP of Technical Services, Stewart Harris. “We would like to thank Coeur for their contribution to the project and will seek a new partner to undertake further drilling.”

Ten holes totaling 2,930 meters were completed - nine holes on the Sarape vein and one hole on the Chiltepin vein. Hole SAR-01 was drilled from the footwall side of the Sarape vein to test both the La Nube vein and the lower levels of the Sarape vein. The hole intersected the La Nube vein but failed to intersect the Sarape vein. Holes SAR19‐02 through SAR19‐09 were drilled from the hanging wall side of the Sarape vein and each intersected the vein. These nine holes tested the Sarape vein along 380 meters of strike length and to a maximum of 450 meters down‐dip. Hole CHI19-01 tested the eastern extremity of the Chiltepin vein and returned no significant results. 

The Sarape vein has a complex, multi-episodic emplacement history with two phases of quartz (white and yellow/green) and two phases of carbonate (grey and white). Gold and silver mineralization is associated with both quartz phases and is best developed between 100 and 350 meters below surface where the vein dilates into a wide fissure vein before it narrows at depth.

Vein textures, gold-silver values, pathfinder elements and vein dilation indicate a prospective boiling horizon between 100 and 350 meters below surface in the drilled area. Holes SAR19-04 and SAR19-06 contain the best developed banded quartz-carbonate textures with rare quartz pseudomorphs of bladed calcite. Only three holes are interpreted to have tested this target level over a strike length of 150 meters. The balance of the six kilometer Sarape vein, including areas of anomalous pathfinder geochemistry, vein splays and flexures, remains untested. Evrim will refine these targets and seek a partner to undertake initial drill tests.

Work completed in 2018 included detailed mapping of the veins and surrounding area, sampling, and an airborne magnetic and radiometric survey. Systematic channel sampling has shown that the western portion of both veins contains barren white quartz and calcite that are interpreted to be a late, shallow part of the system. The eastern portion of the Sarape vein includes a separate phase of low-temperature, tan green quartz that grades from 0.10 to 3.63 g/t gold and individual samples at the Chiltepin vein assay from trace to 3.66 g/t gold.
