Highlights
- All holes drilled so far have crossed a continuous mineralized zone over 450 m in strike, where a quartz vein with sulfides exhibits a downdip extension of over 150 m. The vein’s projected extension is 900 m.
- Thus far, the results acquired in the mineralized quartz vein demonstrate an average apparent thickness of 0.71 m and a weighted average grade of 6.27 g/t Au, with values in enrichment zones up to 20.11 g/t Au.
- The Aurora mine recuperation is continuing, and the tunnels are projected to be drained within 45 days, after which the Company plans to start preparing for production.
- Drilling at the Aparecida brownfield has intercepted gold mineralization twice at the Fortaleza vein, which has an estimated extension of no less than 400 m. Results from the drilling at Aparecida are anticipated in the coming weeks.
- Drilling in Quintanillo may increase the length of the main Aurora vein to over 2 km.
- The Company’s second phase of ground geophysics is happening, with an extra 8,400 m anticipated to considerably expand the projected extensions of observed and established gold mineralization in Botella and Aparecida.
Aurora Mine, Drilling and Production
The aim of the drilling activity at the Aurora mine title is to define the depth and extension of the gold-mineralized quartz vein, which had been prospected for artisanal mining years ago, to support a production plan of 50 tons per day in the first phase implementation.
The Company has secured all the required licenses to work at this level of production, and the mine plan can be expanded based on the mineralization.
A minimum of two drill holes was or is scheduled to be done per section in 50-m intervals, with the aim of reaching the mineralized vein at two levels. The results are expected to inform a production plan so as to estimate the rock tonnage per day.
Drilling in Quintanillo and 43-101 Report
The projected extension of the main Aurora vein is 900 m, with 450 m already established. Ground geophysics specify that there could be continuous mineralization in Quintanillo, the brownfield south of the Aurora title; if these structures are continuous, the projection is that the extension of the main vein of Aurora would touch 2.1 km.
This first phase of drilling, which is fully funded, commenced in August 2021. Though the Company anticipated 8,000 m of drilling to have been finished by the end of 2021 to prove a mineral resource in a 43-101-compliant report, a heavier than usual rainy season caused the completion to be delayed until Q1 2022.
