Southern Hemisphere geophysical survey wins over | Australian Markets

Southern Hemisphere Mining’s current deep penetrating magneto-telluric (MT) geophysical survey has indicated a probably important copper-gold deposit at its Curiosity goal, which is an element of the company’s flagship Llahuin copper-gold-molybdenum project, 350 kilometres north of Santiago in Chile.

The company says the MT 3D inversion model outlines an space of low resistivity at its Curiosity goal that extends for more than 1400 metres under floor. The model has efficiently outlined a clear reference to Southern Hemisphere’s earlier litho-geochemical depth goal modelling and induced-polarisation geophysical knowledge.

The co-incident relationship between the three exploration sources will need to have gave the impression of a profitable trifecta to market punters, who at present piled into the shares to spice up the price by an spectacular 75 per cent. The shares surged to a high of 3.5 cents on robust volumes of more than 20 million shares traded.

The new magneto-telluric 3D inversion model outlines an space of low resistivity, extending over 1400 metres under floor, which, bolstered by our geochemistry and shallow drilling outcomes reveal Curiosity’s potential to host a important copper-gold porphyry deposit. This research has elevated the potential to grow the copper mineralisation footprint within the southern half of Llahuin considerably past the present Central Cerro and Ferro open pit model deposits.

Stowell mentioned the configuration of the Curiosity MT goal is remarkably just like an MT goal on the giant Valeriano porphyry copper-gold deposit in Chile operated by Atex Resources.

The Curiosity goal is within the Southern Porphyry prospect. The goal sits 550 metres under the earlier Santa Maria gold workings and is about 1km in diameter and 2km deep.

The Curiosity goal is supported by a soil geochemistry anomaly at floor and two shallow drill holes that produced drill intervals of 164m at 0.16 per cent copper-equivalent from 2m and 106m operating 0.13 per cent copper-equivalent from 28m.

A 2m hit going 1.45 per cent copper-equivalent from 168m was a additional encouraging outcome.

Management says floor geochemistry and topography spotlight the transition to gold-dominated epithermal mineralisation southeast of the goal space that matches a customary porphyry model of a giant goal at depth.

Porphyry deposits can usually comprise bulk-scale operations with big tonnage, low-grade, simple to mine deposits that may stretch from floor to deep underground.

The company plans to drill check the MT resistivity goal with three to 6 deep holes. The first gap will likely be collared from an current drill pad and drilled to 1400m to intersect the MT and modelled goal zones. Drill planning is in progress.

An MT survey is an electromagnetic geophysical methodology for measuring {the electrical} resistivity of the earth’s sub-surface. The surveys had been used to establish some world-class copper porphyry deposits within the area, together with Atex Resources’ 61-square-kilometre Valeriano deposit in northern Chile.

Southern Hemisphere’s current drilling program has sought so as to add scale to a copper useful resource that consists of 169 million tonnes grading 0.4 per cent copper-equivalent for 680,000t of copper-equivalent materials, which was measured underneath the 2004 JORC tips.

The company just lately nailed a sequence of spectacular copper hits up to 128m thick as half of its 2024 program, which consisted of 2728m throughout 26 holes at Llahuin.

Results from the drill program comprised the massive 128m hit stretching from a depth of 16m, which returned a grade of 0.41 per cent copper-equivalent ending in mineralisation. This included a 32m part going 0.57 per cent copper-equivalent from 66m.

An additional 30m operating at 0.42pc copper-equivalent from floor and 26m at 0.56 per cent copper-equivalent from 40m to finish of gap rounded out the spectacular thick shallow hits.

The outcomes continued the run of thick drill intervals within the South American nation famend as the worldwide chief in copper manufacturing.

Management says many holes led to mineralisation and a diamond drilling marketing campaign within the first half of this 12 months will goal the mineralisation for depth extensions. The program additionally prolonged the project’s strike size 300m to the southwest, stretching it from 1.9km to 2.2km.

Mineralisation stays open in that direction and the company is totally targeted on additional drill testing to maximise the project’s full potential.

Management additionally stays targeted on the ground that lies between its Cerro and Ferro deposits, which is called the Cerro-Ferro hyperlink. The space has returned soil samples operating about 1000 components per million copper.

An up to date useful resource is deliberate for this 12 months and can set up a 2012 JORC-compliant up to date mineral useful resource. With many thick intervals from floor or shallow depths, Southern Hemisphere feels it has a compelling alternative to bolster the useful resource with near-surface tonnes and supply for a potential open pit operation on the project.

Notably, water has been intersected in each gap drilled and testing signifies it to be a contemporary source. This gives the potential to supply all or the majority of the water required for mining.

Southern Hemisphere’s Chilean project appears to have gained a leg-up from this latest survey outcome and the company will likely be eager to unleash a drill rig on the project to check what lies more than a kilometre beneath.
