The company is impressed with the results which indicate that high grade ore may be available for simple, low cost surface mining on the project.
Antilles Gold Ltd () received strong high grade drilling results up to 27.5 meters at 7.2 g / t gold over 146 meters at the La Demajagua gold / silver deposit in Cuba.
Approximately 10,000 meters in 90 holes of the current 15,000 meter program have been drilled, and completion is expected in early August 2021.
In the 27.5 meter intersection there was 7 meters at 16.94 g / t while the same hole also returned 9.5 meters against 188.5 meters at 3.77 g / t.
Results from 14 of the 17 core holes have been analyzed to date along with other highlights from:
- 31.5 meters at 4.95 g / t from 133 meters including 2.8 meters at 29.9 g / t;
- 3 meters at 25.5 g / t from 80.5 meters including 1.5 meters 40.4 g / t;
- 31 meters at 4.97 g / t from 112 meters including 5 meters at 11.02 g / t;
- 20 meters at 6.3 g / t from 148 meters including 3.5 meters at 12.05 g / t; and
- 12 meters at 8.35 g / t from 77.5 meters including 3 meters at 19.25 g / t.
Silver is also evident in many intersections with grades up to 736 g / t.
Satisfied with the results
Antilles Gold Executive Chairman Brian Johnson said cost of surface mining at La Demajagua.
High grade mineralization
According to the company, results to date have reflected high grade mineralization evidenced in 50,000 meters of drilling in the La Demajagua ore body undertaken by Canadian mining companies.
Samples are being analyzed at the Activation Laboratories in Toronto.
The current drilling program and a 10,000 meter infill program slated for early 2022 are aimed at establishing JORC compliant resources and finalizing planning for the proposed surface mine at La Demajagua.
Approximately 2,000 kilograms of representative drill core will be airlifted to a laboratory in Australia or Canada around October 2021 for metallurgical testing and production of concentrate samples for commercialization.
Part of the bankable feasibility study
Additional holes will be drilled in August / September 2021 for geotechnical and hydrogeological studies, which will be part of a Bank Feasibility Study (EBF) for the proposed open pit mine.
The BFS will be compiled by an Australian engineering group and is expected to be completed in time for a development decision for the La Demajagua mine in the fourth quarter of 2022.
