- Maricunga Project
- Maricunga (DFS)
Vancouver, British Columbia - Bearing Resources Ltd. ("Bearing" or the "Company") (TSX Venture: BRZ) (OTCQB: BRGRF) (FRANKFURT: B6K1) has received results from Li3 Energy Inc (“Li3”) from the pump tests at the Maricunga lithium brine project located in Chile (the “Maricunga Project”). Bearing has entered into a definitive agreement to acquire Li3 and its interest in the Maricunga Project (the “Li3 Definitive Agreement”). Li3 currently holds a 17.7% interest in the Maricunga Project along with Minera Salar Blanco (“MSB”) and Lithium Power International Limited (“Lithium Power”) at 32.3% and 50% respectively pursuant to a joint venture arrangement (the “Joint Venture”). Under the terms of the Joint Venture, Lithium Power has agreed to fund exploration and development costs with both Li3 and MSB having a free carry until the completion of a definitive feasibility study.
Maricunga Project – Pump Test Results
Results from a sustainable pump test drilled in the centre of the “old code” Cocina tenement were initially released by Lithium Power on February 23rd, 2017. Pump test well P4 was drilled down to 180 metres with testing focused on production from depths of 66 metres to 180 metres to test the productivity and flow rates deeper within the salar. Over the 30-day period, flow rates and brine grades were closely monitored and stable over the observation period, with flow rates varying between 24 and 25 litres per second (L/s) and grades averaging 945 mg/L lithium and 6,924 mg/L potassium. Average grades from sampling brine over the 30-day period, which showed only minor variation, were from sampling of the lower aquifer (66 metres to 180 metres) and therefore excluded brine from the higher grade upper aquifer zone.
Prior pump test wells, namely P1 and P2 located in the Litio tenement, returned average rates of 38 L/s over 14 days and 37 L/s over 28 days respectively. Of note, these flow rates were from a combination of the upper and lower aquifers combined, versus P4 which focused solely on the lower aquifer.
Jeremy Poirier, President and Chief Executive Officer of the Company commented: “Overall we are very pleased with the results from sustained pump testing of well P4 which demonstrated both stable flow rates and grades over the period. This demonstrates the productivity of the Maricunga salar and more specifically, the extractability of brine from depth which coincides with the depth of the majority of our Phase 1 drill program which tested down to around 200 metres.”
Drilling was by rotary drilling that provide cuttings for lithological logging and for geological interpretation.The brine sample was collected in a clean plastic bottle and filled to the top to minimize air space within the bottle. The University of Antofagasta in northern Chile was used as the primary laboratory to conduct the assaying of the brine samples collected as part of the drilling program. They also analyzed blanks, duplicates and standards, with blind control samples in the analysis chain.
Pumping test data is continuously monitored via a fluid flow meter at the well head and a series of piezometric wells and monitoring wells spaced at appropriate intervals from the well to measure fluid drawdown both in the upper aquifer and the target aquifer. Data are collected by data loggers and by daily manual inspection. Brine discharge is also monitored using a V-notch weir located approximately 1,200 metres from the well. Brine samples are collected daily from the V-notch discharge to assay variations in brine chemistry over the duration of the pump test. The assay procedures for the pump test samples are the same as for the brine samples collected from drill holes.
Additional details of the QA/QC program and sampling procedures are provided in the Lithium Power press releases mentioned.
