Azure Minerals Limited has advised that it is about to start drilling campaigns on both its new flagship Oposura zinc-lead-silver and the highlyprospective Sara Alicia gold-cobalt projects in the northern Mexican state of Sonora.
- Drilling expected to start on both projects within a week.
- Two drill rigs at Oposura will enable resource estimation in early 2018.
- Sara Alicia drilling to test high-grade gold-cobalt mineralisation.
The projects, both recently added to Azure’s Mexican portfolio, have received all required approvals from the environmental authorities and drilling is expected to start within a week. OPOSURA PROJECT Azure’s first drilling program at Oposura is designed to enable the company to complete a Mineral Resource estimate towards the end of March 2018. The drilling will cover an area of 1400 m x 400 m to confirm the extent of the mineralised zone, as defined by historical exploration. It is anticipated that about 120 holes will be drilled, totalling approximately 7000 m, with an average depth of circa 60 m per hole. Due to the horizontal nature of the mineralised zone and the slope of the overlying topography, it is likely that the maximum hole depth will be about 120 m. Additional drilling will also be undertaken to explore potential extensions further to the north of the currently known mineralised zone. Based upon historical exploration reports, the company has previously announced an Exploration Target of: 2.5 - 3.0 million to grading 10.0% - 12.0% Zn+Pb* *This Exploration Target (refer ASX announcement of 18 September 2017) is conceptual in nature, but is based on reasonable grounds and assumptions. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
Azure has constrained this Exploration Target to the eastern half of the project area where zones of massive sulfide mineralisation outcrop extensively over an east-west strike length of approximately 1400 m and where historical drilling (approximately 100 diamond core holes) and exploratory underground mine development has demonstrated the presence and continuity of the mineralised zone over 400m in a north-south direction.
