Arrow Minerals identifies Strickland VMS targets through data reanalysis
In parallel with Strickland, Arrow continues to explore for gold in Burkina Faso
Arrow Minerals Ltd (ASX:AMD) has identified strong signatures consistent with volcanogenic massive sulphide (VMS) copper-gold mineralisation in detailed reanalysis of historical soil, reverse circulation (RC) and aircore (AC) geochemical data at the Strickland Project in WA.
The company’s geological team has analysed the large dataset of more than 40,000 soil, shallow RC and AC samples that have been collected since November 2016.
Results show that the large Arrow tenement holdings can be divided into two blocks – a northern block prospective for orogenic gold deposits and a southern block that contains three discrete areas hosting anomalous geochemistry typical of copper-gold VMS and intrusive hosted deposits.
The copper-gold potential is the focus of ongoing work at Strickland.
Fast-track exploration program
Managing director Howard Golden said: The nearby Perrinvale and Rover discoveries and general geological similarity to the major Golden Grove VMS camp add significantly to our confidence in these targets.
“These results will fast-track Arrow’s targeted exploration program to uncover the VMS potential at Strickland.
“Exploring this high-quality copper-gold-base metal project in addition to our recent Dassa gold discovery in Burkina Faso will give our shareholders excellent exposure to further discoveries.”
Shares are up 20% to 0.6 cents.
Precious and base metal anomalism targeted
Archaean VMS deposits, the majority of which are found in Canada, have also been discovered in Western Australia, including the recent discoveries of Perrinvale by Cobre Limited (ASX:CBE) and Rover by Twenty Seven Co Ltd (ASX:TSC).
They typically occur as lenses of polymetallic massive sulphide that formed at or near the original seafloor in submarine volcanic settings and are hosted in either volcanic or sedimentary rocks.
This environment is exemplified by the greenstone terranes in the Yilgarn Craton where Strickland is located.
Arrow’s three anomalous areas at Strickland (Target T-06, Target T-08 and Target T-14) have different combinations of highly anomalous gold, silver, base metals and other pathfinder elements that typify VMS environments.
The recognition of multi-element anomalies with copper-gold VMS and intrusive-hosted potential at three sizeable targets highlights the significant exploration potential of the Strickland project.
Arrow plans to progress work in Western Australia as well as in West Africa as the COVID-19 pandemic recedes in the coming months.
Electrical geophysical surveys will be planned for Strickland to pinpoint potential massive sulphide sources of the already well constrained geochemical anomalies at the three targets.
In parallel with Strickland, Arrow continues to explore for gold in Burkina Faso, focusing on the recent Dassa discovery in the west of the country.
These complementary projects in Western Australia and Burkina Faso will allow Arrow year-round access to projects during their respective field seasons.
The next step at Dassa will be follow-up reverse circulation drilling to fill in an undrilled gap in a 3 kilometre strike length of gold mineralisation defined in previous drilling.
Arrow still has A$300,000 of prepaid drilling available for the next round of work at Dassa.
The recognition of two highly prospective jurisdictions in West Africa and Western Australia puts Arrow in an excellent position to move ahead with targeted exploration for gold and copper-gold during the remainder of 2020.
