Bryah drilling uncovers intriguing Horseshoe Lights analogue
Link copied to
Special Report: Bryah has identified a volcanogenic massive sulphide target at its Windalah project that is similar to the nearby Horseshoe Lights copper-gold deposit.
Its recently completed aircore drilling program in the Windalah East prospect intersected anomalous copper and gold along with key pathfinder minerals, including up to 455 parts per million arsenic, 48.5ppm antimony and 12.7ppm molybdenum.
These are commonly associated with VMS deposits.
Bryah Resources (ASX:BYH) says the results provide a coherent exploration target over a strike length exceeding 500m that is open to the north-west of the aircore drilling program.
This zone is also situated over an airborne electromagnetic target identified in 2018, providing the company with a bedrock target to test using deeper reverse circulation and diamond drilling.
“The discovery of this downhole geochemical anomaly is testament to excellent geological processes the Bryah technical team has been applying to the project and confirms the potential for a VMS copper-gold discovery on Bryah’s highly prospective tenement package,” managing director Neil Marston said.
“We look forward to the next exciting phase of copper-gold exploration at Windalah, which will include a program of targeted RC and diamond drilling planning for early 2021.”
Bryah had completed the 67-hole program totalling 5,999m over four prospect areas though it has only revealed results from the 27 holes drilled at Windalah East to test a large soil geochemistry anomaly.
These holes supplemented initial aircore drilling carried out in March this year along with drilling to test a nearby gravity anomaly.
Windalah lies within the Mars Dome, which forms part of a series of double plunging anticlinal dome structures in the northern Bryah Basin.
Sulphide mineralisation has been located on the southern limb of Mars Dome that has been confirmed through mapping, drilling and comprehensive downhole geochemistry.
The company believes the mineralising system is analogous to the historical Horseshoe Lights gold-copper mine that produced 3.3 million tonnes of ore grading 2.9 grams per tonne gold and 1.7 per cent copper since its discovery in 1946 till production ended in 1994.
