Orocobre (ASX: ORE, TSX: ORL) provides the following update on the brine sampling of diamond core holes CAU20 and CAU21 in the NW Sector of the Cauchari joint venture property located in Jujuy province, Argentina.
As quoted in the press release:
- These results from CAU20 and CAU21 demonstrate the Phase III infill drilling and resource conversion program is on track to deliver Measured and Indicated Resources by early 2019
- Systematic brine sampling completed in holes CAU20 and CAU21 respectively averaged 629 mg/l lithium and 4,537 mg/l potassium from 113-318 m depth and 607 mg/l lithium and 4,691 mg/l potassium from 125-265 m in the north of the NW sector
- Drill holes encountered predominantly sandy sediments and gravels that are expected to have high drainable porosity and excellent permeability to support high pumping rates
- Holes confirm the continuity of the brine body between previous drill holes in the NW Sector CAU17, CAU18, CAU07 and CAU16
- Very low Mg/Li ratios of 2.1:1 and 2.2:1 respectively, and low SO4/Li ratios of 24:1 and 23:1 respectively, similar to that demonstrated during pumping of CAU07 – excellent for conventional brine processing
- CAU24, completed in the southern portion of the NW Sector, confirms that brine resources continue over a 20 km distance north to CAU18 and are generally contained in the permeable sand dominated units.
