Rimfire Pacific Mining NL (ASX:RIM) has started diamond core drilling at the Sorpresa Development Project earn-in with Golden Plains Resources (GPR) within the Lachlan Fold Belt of central New South Wales.
Data from this drilling program will assist in the development of the geotechnical and metallurgical design parameters for the project.
The core drilling will provide geotechnical engineering data that will allow the determination of the optimal pit wall slope design parameters for the mine plans.
The metallurgical drilling will provide samples for further testing to refine ore processing options.
“Information to support development”
Rimfire managing director Craig Riley said: “It is exciting to recommence drilling after delays due to impact of recent significant rain at the site and State Government movement restrictions due to the COVID pandemic.
“This program will importantly provide significant information to assist with Rimfire’s objective of obtaining a Development Consent for the Sorpresa Project.”
Metallurgical samples collected will also provide various types of ore and waste samples for geochemical analysis.
This will form part of the Environmental Impact Assessment (EIA) that is required to obtain the Development Consent from NSW Government authorities for the Sorpresa project.
In May 2020, Rimfire signed an earn-in agreement with GPR covering an area of 103 square kilometres covering Sorpresa and the surrounding area.
