Rincon Resources Limited (ASX:RCR) has a significant new target through positive results from geophysical modelling at its 100% owned South Telfer Copper-Gold Project, located in the Paterson Province, Western Australia.
The Recurve target is located along the highly-prospective Hasties-Grace Gold Trend, within the company’s Westin tenement area, 30km southwest of the giant Havieron deposit (5.5Moz Au2) and 40km southeast of the world- class Telfer Gold Mine (+32Moz Au)
Recurve is another high-priority copper-gold target like the recently defined Mammoth target in the company’s South Telfer Copper-Gold Project land holdings,” Managing Director, Gary Harvey, said.
“This time, the target is located along the highly prospective Hasties-Grace Trend, a known mineralised shear and fold corridor trending northwest and south- east, passing through all of Rincon’s South Telfer tenement areas. A similar regional shear runs along the west side of Rio Tinto’s Winu copper-gold deposit located to the northwest.
“Recurve is also located just 15km southeast of Paterson Resources’ (ASX: PSL) high-grade Grace-Bemm deposit, where recent drilling by Paterson intersected 6m @ 9.3g/t, 7m @ 11.0g/t, and 4m @ 9.2g/t gold (refer to ASX: PSL Announcement dated 24 October 2022).
At 1.7km long, Recurve is the largest and best-defined untested copper-gold target along the Hasties-Grace Trend. Our next steps include a heritage clearance survey and detailed ground gravity and passive seismic surveying to further define the target ahead of drill planning.”
Reinterpretation of existing VTEM and Gravity data by consultants Resource Potentials, using a combination of modelling techniques and interpretation of results, has elevated Recurve to a high-priority copper-gold target for drill testing.
Recurve is an interpreted zone of extensive deep weathering, thought to be related to oxidised sulphides, formed along a flexure in a regionally mineralised shear zone and adjacent to an interpreted deep-seated felsic intrusive body.
Encompassing a surface area of approximately 1,700m by 350m, Recurve is second largest untested copper- gold target which the vompany has defined in recent months; Mammoth being the largest. However, Recurve is the largest of several copper-gold targets located along the Hasties-Grace Gold Trend, defined by a regional shear zone and associated folds, and is just 15km southeast along strike of the high- grade Grace-Bemm gold deposit held by Paterson Resources Limited, where recent drilling by PSL intersected multiple high-grade intersections, including 6m @ 9.3g/t, 7m @ 11.0g/t, and 4m @ 9.2g/t gold.
Modelling of VTEM electromagnetic data to generate conductivity-depth geometry in the subsurface indicates that an extensive weathered zone occurs along the shear zone where it is curved to form a flexure zone, where weathering locally reaches a depth of at least 300m (possibly to 885m) and indicates that the average depth of transported sand cover is about 110m or less below land surface.
Gravity 3-D inversion of combined regional ground gravity and Falcon airborne gravity gradiometry data was used to define a gravity low body interpreted to be caused by a felsic intrusive body, which could have intruded along the same prominent flexure zone. Such a geological setting has potential for the development of an associated mineralised breccia/stockwork system within the shear.
The current geophysical modelling and interpretation results are preliminary, with detailed ground gravity and passive seismic surveys planned to further define and enhance the geometry and depth of the Recurve Target before proposed drilling in early 2023.
