[{"type":"text","content":" VANCOUVER, British Columbia, Feb. 26, 2020 (GLOBE NEWSWIRE) -- Sonoro Metals Corp., (TSXV: SMO | OTCQB: SMOFF | FRA: 23SP), (“Sonoro” or the “Company”), announces the completion of a comprehensive technical assessment on the 17 zones of gold mineralization identified to date at its Cerro Caliche project in Sonora, Mexico. The purpose of the assessment was to evaluate the potential for a material increase in the current 201,000 oz AuEq resource as well as the potential to delineate further resources throughout the mineralized zones. A program combining reverse circulation and core drilling for up to 50,000 meters of drilling will be carried out in several phases. The next phase, Phase III, targeting approximately 10,000 meters of drilling, will commence in March 2020. In Phases I and II of the drilling program, a total of 96 holes totaling 10,328 meters were drilled and assayed for an average drill hole length of 107.6 meters, all inclined. The combination of historic and current exploration drilling totals 23,679 meters in 212 drill holes, in addition to more than 6,000 surface samples. Drilling to date has outlined shallow, bulk tonnage gold mineralized zones with grades similar to operating heap leach mines in the region. In addition to the continuation of reverse circulation drilling, core drilling will also be employed during Phase III to more accurately determine the dimensions of the gold-mineralized geologic structure. These mineralized structures are common within the shallow gold-silver resource partially defined by the recent reverse circulation drilling. Furthermore, core drilling will be employed to explore the potential for higher-grade gold mineralization in the vein zones that structural analysis asserts may be present at greater depths within the veins. In general, mineralization models indicate that deeper parts of low sulfidation epithermal deposits are more likely to contain higher-grade precious metals. Silver/gold ratios vary with physical elevation within the mineralized vein zones. These silver/gold ratios can be used to determine the vertical position of specific mineralization within the structure. An example of this is found in drill hole SCR-044 in the El Colorado zone, where the mineralized intercept at the lowest elevation contains 12.2 m of 11.3 g/t AuEq and a silver/gold ratio o...
