Exploration Resumes At Bramaderos In Ecuador
Sunstone Metals (ASX: STM) has reported further outstanding drilling results from the Viscaria Copper Project in northern Sweden.
Viscaria is owned by NASDAQ Stockholm-listed Copperstone Resources AB, in which Sunstone has a ~25%. Sunstone is actively involved in Copperstone through board representation and participation in the Copperstone Technical Committee.
Eight diamond drill holes have now been completed on the Viscaria D Zone North shoot in the past eight months and the results to date strongly reinforce the interpreted geometry of thicker and higher-grade steep shoots extending to depth. It is expected that multiple shoots will be defined as drilling progresses.
Latest drilling highlights include:
- 18.9m at 1.3% copper from 468.1m in hole VDD 212
- 7.1m at 3.8% copper from 615.2m in hole VDD 213, including;
- 0.6m at 20.1% copper from 617.6m in hole VDD 213
- 9.3m at 1.0% copper from 689.5m in hole VDD 215
- The VDD 213, 214 and 215 intersections are outside of the area of the existing Mineral Resource estimate.
Copperstone CEO, Michael Mattson, confirmed these were very exciting drill results.
“These very convincing results encourage us to continue our drilling campaigns in the Viscaria project with a planned re-opening of the mine in sight,” Mr Mattson said.
“The D-zone is increasing by every drill hole, and the Viscaria Copper project is hence growing steadily. With these indications of high-grade copper, our ambition is to further upgrade the already large mineral resource.
“As a consequence of the growing project and increased mineralized drill core information, we will need to put further investments and time into the technical part of the environmental permit application, and in parallel I am looking forward to strengthening the organization further.”
Meanwhile, Sunstone reports that exploration has resumed at the Bramaderos gold-copper projectin southern Ecuador, with targets being refined through desktop assessments of re-processed data, and through new exploration programs including trenching, detailed mapping and rock chip sampling, and detailed soil sampling.
Drilling is expected to start at Bramaderos in September.
Sunstone said it is in close contact with local stakeholders to manage the exploration program and manage the risks associated with the coronavirus pandemic. Some restrictions have been eased in Ecuador to support a re-opening of the economy.
