Greatland Gold Announces Positive Results from Electromagnetic Survey at the Bromus Project
Greatland Gold plc, the mineral exploration and development company based in Australia, is pleased to announce significant developments at the Company’s Bromus project.
- Ground electromagentic survey is underway to identify nickel sulphide targets
- Preliminary results are positive. We have identified a very significant bedrock conductor (an area of highly conductive material in the bedrock) and several others which require further investigation
Callum Baxter, CEO, commented: “We are pleased to announce that a ground electromagnetic survey has commenced at the Bromus Project, targeting nickel sulphides. Data quality is extremely good and productivity is outstanding. Initial data has identified a very significant bedrock conductor in the north of our target area, as well as several others that require further investigation. We are excited to have succeeded in identifying significant bedrock conductors so early in the programme.”
Bromus Project, Western Australia
The Bromus project is located in southern Western Australia, approximately 25km south west of the town of Norseman, and covers approximately 112 square kilometres. Several significant clusters of gold and nickel sulphide deposits lie in the region, such as those at Central Norseman, Kambalda and Widgiemooltha. Greatland owns 100% of the project.
Last year, a review of detailed airborne geophysics defined a 4.5km long, nickel sulphide prospective ultramafic, with coherent elevated surface geochemistry to 2,690ppm Ni, in the centre of the Bromus project area. This is a sizeable nickel sulphide target which can be explored with common geochemical, electromagnetic and drilling techniques. Field work confirmed the presence of flow textured ultramafic lithologies and, despite the proximity to other deposits, no previous exploration for nickel sulphides is apparent.
A fixed loop ground electromagnetic survey has commenced over the entire 4.5km strike. The fixed loop technique involves laying out a large transmitter loop and recording the electromagnetic response along grid lines both inside and outside the loop. Here, the loop size is approximately 1.5km x 1.0 km with receiver traverses 100m apart across the ultramafic. High definition ground magnetics are being collected alongside electromagnetic data and the productivity of the field crew is outstanding.
Data quality received so far is extremely good, with excellent ground penetration. Most importantly, a significant bedrock conductor has been identified in the north of the survey area. The conductor is well defined over approximately 400m of strike, representing a sizeable target. We have also identified other conductors which we will investigate further with modelling and Greatlnd will test these drill targets during the coming months.
Additional information will be provided once all data has been received and modelling has been completed. We expect this to take approximately two weeks.
