Gateway Mining Limited (ASX: GML) has mobilised field staff to the 526,000 ounce Montague gold project, located in the Murchison Gold District of Western Australia.
The team will commence site preparation works for a new round of Reverse Circulation (RC) drilling at the new Duplex discovery.
Duplex is located approximately 3.5km south of the cornerstone 163,000oz Au Montague-Boulder Mineral Resource, along the western margin of the Montague Granodiorite Dome.
This next phase of RC drilling will test the full potential of Duplex, both along strike and down-dip, with positive results expected to lead to systematic drilling to enable an initial Mineral Resource calculation. Drilling is planned to commence later in May.
RC drilling completed to date has identified coherent gold mineralisation within the host gabbro unit at Duplex over 250m of strike.
This mineralisation is accompanied by a distinctive alteration consisting of magnetic depletion of the gabbro unit. This distinct negative magnetic anomaly can be traced in existing airborne magnetic geophysics over an additional 500m further to the north, with historical air-core hole GWAC0453 intersecting 14m @ 0.5g/t Au at the end of hole, including 4m @ 1.1g/t Au at the very northern extent of this trend.
The trace of the demagnetised feature in the airborne magnetic dataset demonstrates several “jogs” along the structure.
“We are very excited to be preparing for our next phase of drilling at Duplex, which is emerging as an important new discovery within the Montague gold project,” Managing Director, Mark Cossom, said.
“Our drilling to date has defined the mineralised zone over approximately 200m strike, with air-core anomalism and airborne magnetics indicating the potential for a further 500m strike extent to the north. This new round of drilling will test this northern strike extent, as well as testing for potential depth extensions below the high-grade intercept of 18m grading 5g/t gold returned from hole GRC1022.
“If successful, the results from this program will lead into a more comprehensive drilling campaign designed to underpin the delivery of a maiden Mineral Resource Estimate for Duplex, with the potential to deliver a step- change increase in the existing 526,000-ounce Montague Resource.”
