"We have unlocked tremendous value through the drill bit and there is great potential for significant resource growth in the near term," Bonillas said.
"Our exploration programme defined a high-grade resource and discovered several parallel structures. We look to add the newly discovered structures in our next resource update and anticipate material increase in the mineral inventory," he added.
The estimate was delivered on time and budget and the company is on track to release a preliminary economic assessment in the coming months and make a construction decision before the end of 2022, Bonillas said.
