Rincon Resources (ASX:RCR) reports the latest geophysical modelling at its South Telfer Copper-Gold Project, located in the Paterson Province of Western Australia has defined a ‘significant’ new gold-copper target called Mammoth.
Reinterpretation of existing geophysical aeromagnetic data using 3D inverted magnetic modelling techniques has defined the new target 700m to the northeast of the company’s existing Westin Prospect, located 25km southwest of the ‘giant’ Havieron deposit (5.5Moz Au, 218kt Cu) and 35km directly along strike of the ‘world-class’ Telfer Gold Mine.
Mammoth is the largest of the three new targets defined over a strike length of 15km along the ‘highly prospective’ Telfer-Westin Trend within Rincon’s underexplored Westin tenement area.
The new modelling, completed by independent geophysical consultant Value Adding Resources shows all targets are relatively shallow with the top of Mammoth starting at approximately 85m below surface, with the deepest target ‘Hawkeye’ starting from approximately 310m below surface.
The modelled surface expression of the Mammoth target measures 1,700m in strike length and the widest section measuring 500m.
The modelled source body orientation strikes northwest-southeast and has a moderate southeast dipping plunge.
The current modelling also indicates the Mammoth target extends to a modelled depth of approximately 1,100m vertically below the surface.
The current results are preliminary and geophysical modelling is ongoing with gravity and versatile time-domain electromagnetic data (VTEM) to be incorporated in due course to further refine existing and new targets.
Rincon Managing Director Gary Harvey said Mammoth is new, its big and could be a “real game changer” for Rincon.
“If Mammoth is a plug-like diorite intrusion, like we think it may be, then there is real potential for Havieron style breccia related mineralisation to be wrapped around the margins”
“If Mammoth is a plug-like diorite intrusion, like we think it may be, then there is real potential for Havieron style breccia related mineralisation to be wrapped around the margins.
“There’s more geophysical modelling to be completed before we drill, but this is a tremendous start. We are well positioned to drill in the area once the target is better defined.
“There is significant potential for a new high-grade copper-gold deposit to be discovered at South Telfer, particularly within our Westin tenement area, south of Havieron and along strike of Telfer.
“Exciting times are ahead, aircore drilling is due to commence shortly on the Westin tenements, we’ve increased our landholdings with the Wilki Range tenement acquisition, we have established access and a camp facility, a heritage clearance survey over the Westin area has been completed, and now we’ve defined a significant new Havieron style target next to Westin.”
Mammoth is located 700m northeast of Westin, where historic drillhole WSA08039 intersected 8m @ 3.85g/t Au from 84m (including 4m @ 6.9g/t Au from 88m).
WSA08039 was part of a broad, wide spaced aircore drill campaign by Newcrest Mining (ASX:NCM) in 2008 that tested a section of the ‘highly prospective’ Telfer-Westin from Newcrest’s Ironclad/Dolphy deposits to Rincon’s Westin Prospect.
Within Rincon’s tenements, the drilling identified an anomalous gold-in-bedrock trend over 5km. No drilling has tested the Telfer-Westin trend southeast of Westin.
Only one traverse of aircore holes by Newcrest, the same traverse that includes WSA08039, was drilled across the top of Mammoth with hole WSA08028 intersecting 3m @ 61ppb Au at the end of the hole.
The intercept occurred in mafic dolerite according to the drill log data, although further work is required to confirm the Mammoth source body is a mafic intrusion.
The company reports this is positive, however as it appears to demonstrate the Telfer-Westin Trend has potential to host Havieron-like breccia-related mineralisation associated with intrusive driven hydrothermal systems.
Rincon Resources has a 100% interest in three highly prospective copper and gold projects in Western Australia comprising South Telfer, Laverton and Kiwirrkurra.
Each project has been subject to historical exploration which has identified major mineralised systems which Rincon intends on exploring in order to delineate copper and gold resources.
