Oroco is pleased to report preliminary results from reconnaissance rock-chip sampling and geological mapping at the Vainilla Project in northern Sinaloa, Mexico, including one selective sample from the El Platano breccia pipe that returned 7.57% copper. The Company has also completed a high-resolution drone magnetometry survey over the property.
"While our primary focus remains the advancement of Santo Tomás, the preliminary results at Vainilla support further systematic evaluation of this property," said Oroco CEO Charles Cryer. "The combination of a selective high-grade copper sample at El Platano, widespread alteration and several distinct mineralized prospects provide a basis for disciplined target development. The proximity to Santo Tomás may also offer logistical benefits if future exploration is successful."
Highlights
• Mapping and sampling have advanced the definition of three principal mineralized areas: El Platano, Mazomique and Cristina
• One selective rock-chip sample from a historical working at El Platano returned 7.57% copper; the sample is not representative of the overall grade or continuity of mineralization.
• El Platano is interpreted as a mineralized breccia body hosting copper-iron oxides, secondary copper minerals, precious metal anomalies, quartz-tourmaline brecciation within a broad propylitic alteration halo in andesitic volcanics
• Mapping surrounding Mazomique has identified magnetite-pyrite-chalcopyrite mineralization and copper oxides associated within exo-skarns exposed in previous mining operations
• At Cristina, a structurally controlled breccia is host to anomalous gold, silver, copper and lead
• A property-wide, high-resolution drone magnetic survey has been completed to assist in defining structural, intrusive, porphyry and skarn-related exploration targets.
