Latest Assays Extend Known Strike Length Of Espiritu Silver-Gold System To 700m
Cornerstone Capital Resources Inc. (TSXV-CGP) has continued to grow the Bramaderos gold and copper joint venture in southern Ecuador in which it has a 12.5% interest carried by JV partner and project operator Sunstone Metals Inc. through to the start of commercial production.
HIGHLIGHTS:
- Two latest holes (ESDD008 and ESDD009) at Espiritu extend the known strike length of the silver-gold mineralisation to 700m
- Drill hole ESDD009 intersected 2 significant lodes of silver-gold-zinc-lead mineralisation including:
- 2.5m at 65.9g/t silver, 1.63g/t gold from 369.5m
- 0.5m at 141g/t silver, 0.28g/t gold, 0.52% copper, 2.73% lead and 1.15% zinc from 370m
- 0.6m at 154g/t silver, 6.46g/t gold from 371.4m (only 140m below surface)
- Detailed soil geochemistry has defined several significant anomalous areas to the south-east for drilling
VP of Exploration, Yvan Crepeau, said Espiritu is one of several similar targets within the Bramaderos project area
“These results provide more evidence that Espiritu is a large silver-gold system. It is still early days in the exploration of this system, and we are still developing models for the style and geometry of mineralisation, that will in turn enable us to better target the higher-grade areas,” Mr Crepeau said.
“The early benefits of this approach are seen in drill hole ESDD009, which delivered the highest gold grades we have seen in the system.
“We are seeing the suggestion of groupings of discrete surface anomalies that we believe probably reflect higher grade shoots, and which will be the focus of ongoing work. We will be exploring individual targets within an area 700m x 1,500m. Locally these areas contain very high grades of silver and we are getting closer to understanding the controls on those higher grades.
“Once ESDD011 is completed we will review all data to plan the next phase of drilling. This will include drilling at Espiritu Southeast where Espiritu style veining is present at surface and corresponds with a cluster of silver-in-soil anomalies over a strike length of 400m. Espiritu is just one of several similar targets within the Bramaderos Project area, which require further exploration.”
Assay results and geological interpretation from holes ESDD008 and 9 show multiple silver-gold bearing structures with various orientations with local high-grade mineraliation, including the highest gold grades yet drilled at Espiritu.
Evidence of multiple lodes continues to be identified in drilling. Narrow high-grade zones appear to narrow and thicken, and better mineralisation is interpreted to occur at vein intersections. This is interpreted to generate sub-vertical higher-grade shoots as seen in holes ESDD005 and 006, and to be tested with hole ESDD011 in progress.
Measuring 4,948 hectares, the Bramaderos project is located approximately 130km from the Loja provincial capital in southern Ecuador.
