Sonoro Metals Corp. reported the third and final set of assay results from phase one of the 10,000-metre drilling program at Sonoro’s 100% owned Cerro Caliche gold project in Sonora, Mexico. A total of 45 reverse circulation holes totaling 4,604 meters were drilled during the program confirming a cluster of eight northwest trending gold-dominant structures surrounded by parallel sheeted veinlets and stockwork veinlets. Highlights from the final 14 holes include 12.2 meters of 11.3 grams per tonne AuEq, 4.6 meters of 4.69 grams per tonne AuEq and 12.2 meters of 0.95 grams per tonne AuEq. Together with the earlier drilling results announced in Sonoro’s news releases dated November 9, 2018 and December 5, 2018, the combined results from the phase one drilling program confirm shallow, low grade, bulk tonnage gold mineralized zones in supergene oxidized sedimentary and igneous rock units. Subject to metallurgical confirmation, the gold mineralized zones appear amenable to heap leach extraction of precious metals with deep oxidation. The average gold grade of intervals reported is observed to be similar to other gold heap leaching mining operations in the region. Sonoro has also received and analyzed the databases from Corex Gold Corp. and other operators that carried out historical drilling programs at Cerro Caliche since 2007. These operators completed an aggregate of 116 drill holes totaling 12,442 meters of drilling, in addition to over 4,000 surface samples. The combination of historic and current exploration programs totals over 17,000 meters of drilling in 161 drill holes and over 6,000 surface samples. The mineralized zones are named after historic mine workings situated within each zone, from east to west, as follows; Las Abejas, Chinos NW, Japoneses, Los Cuervos, El Quince, Cabeza Blanca, Guadalupe, and El Colorado. Results from 19 drill holes in the Cabeza Blanca/El Colorado/Guadalupe zones outline a linear central vein structure with sheeted to stockwork associated mineralization. Results also confirm lateral continuity of over 500 meters for both the Cabeza Blanca zone and its parallel companion, the Guadalupe zone. Furthermore, a high-grade interval of 6.09 meters of 21.5 g Au per tonne was cut near an intersection between the Guadalupe and El Colorado zones. The 19 holes completed in the Japoneses and Cuervos zones indicate one continuous structure extending approximately 1.2 kilometers. Detailed cross sections have been constructed to aid in structural interpretation. Host rocks cut by the gold mineralization include quartzite of Jurassic age and early Tertiary biotite granodiorite porphyry and minor rhyolite. The Abejas zone is the most northeasterly gold mineralized structure at Cerro Caliche. A total of 5 holes have been drilled at Abejas, confirming host rocks like those identified in the Japoneses-Cuervos zone. Short, air track drill holes are planned for the nearby Chinos NW zone to confirm suspected shallow gold mineralization. Four historic drill holes in the zone’s southern extension identified stockwork gold mineralization. Distances between each mineralized zone range from 120 to 400 meters with widths of each mineralized zone reaching up to 60 meters and lengths of approximately 800 meters.
