Sonoro Gold Corp (TSX-V:SGO, OTCQB:SMOFF) has released positive results from an underground channel sampling program at its Cerro Caliche project in Mexico, which it says validates the firm's plans to develop a heap leach operation there.
The results provide important geological data from a 100 metre (m) section at the south end of the Cabeza Blanca vein as it enters the El Colorado zone, and all the results, as well as more than 7,200m of new drilling data, will be included in an updated resource estimate.
Highlights from the channel sampling included 2m averaging 7.863 grams per ton (g/t) gold across the Cabeza Blanca vein with 3.5 meters averaging 3.071 g/t gold.
"The positive results from the Cabeza Blanca South tunnel sampling program continue to highlight the intrinsic value of the project and underline the board's ongoing commitment to develop the proposed heap leach mining operation at Cerro Caliche," said John Darch, Sonoro's chairman, in a statement.
Kenneth MacLeod, Sonoro's CEO, added: "The underground channel sampling yielded valuable data that we anticipate will augment the data obtained from our recent surface sampling and drilling programs completed in the same area.

"As previously announced, an updated resource estimate is being prepared and will incorporate all geological data to date."
Cerro Caliche sits in the Cucurpe-Sonora Mega-district of Sonora, Mexico. Multiple historic underground mines were developed on the concession, including Cabeza Blanca, Los Cuervos, Japoneses, Las Abejas, Boluditos, El Colorado, Veta de Oro and Espanola.
At the Cabeza Blanca vein zone, two historic tunnels were developed in the 1950s, with the northern tunnel continuing around 600m on a 10 northwestern trend and the southern tunnel continuing around 350m on a 15 southeastern trend to the El Colorado zone.
Sonoro Gold is a publicly listed company, which has the near-development-stage Cerro Caliche project and the exploration-stage San Marcial project in Sonora state.
