Brazilian-focused Orinoco Gold is shifting its attention to finding potential high-grade silver deposits at its Cascavel project.
In 2013, Orinoco confirmed the presence of a large gold system at Cascavel. At the time, Orinico also uncovered rock chip results up to 4,234 grams per tonne silver and a high-grade silver intersection of 17.56 metres at 1292gpt silver at the project.
Drilling was only focused on gold but the potential for high-grade silver deposits underneath and to the south of Cascavel is real and deserves greater attention, the company said.
Orinoco is now carrying out an extensive review of the exploration data available for silver and base metal anomalies.
“The more we work with the data we have compiled during the last few years the higher our expectations are about the system’s potential,” Orinoco’s Head of Exploration Dr. Marcelo de Carvalho said.
“The system is open, strong and carries a multitude of different metals.
“The next steps for the exploration of this system will be focused on detailed mapping and sampling of the main faults, particularly where those faults intercept thick dolomite packages like the Cascavel Dolomite
.
He said a detailed geophysical survey was also being discussed and will have the aim to identify the ore signature.
“Met tests on the silver mineralisation is also part of the proposal. Drilling will be proposed after mapping and geophysics,” he added.
Cascavel lies within Orinoco’s Faina goldfields project in the State of Goiás in central Brazil.
