Infinity Mining has been granted a five-year exploration licence extension for one of the key tenements at its Panorama project in the Pilbara where the company is targeting its Brisbane nickel prospect.
Last year the explorer collected a total of 35 samples at the site with assays showing results of up to 7636 parts-per-million nickel and 8918ppm chromium consistent with previous geochemical results.
Infinity’s exploration strategy for the prospect is targeting the potential of quartz vein-hosted gold, conglomerate-hosted gold, ultramafic nickel-copper sulphides and volcanogenic-hosted massive sulphide deposits.
The Brisbane prospect was first identified in 1969 by Planet Metals that conducted a geological mapping and rock chip sampling program at the site returning results of up to 6319ppm nickel and 14800ppm chromium.
The area sits along the basal contact of an ultramafic intrusion of the Dalton Suite that is considered to be an important host rock for nickel. The recent sampling program also unearthed anomalous levels of zinc up to 2569ppm.
Infinity recently conducted a helicopter electromagnetic survey over the Panorama project that identified a prominent conductive target 350m east of the Brisbane prospect that the company believes could host a buried nickel sulphide system. The final interpretation of the data is currently underway.
Infinity Mining Chief Executive Officer, Joe Groot said: “The extension granted on E45/4779 is great news for Infinity. The company is excited about drilling at the Brisbane nickel project and further reconnaissance work in the licence area.”
The explorer says once access tracks into the prospect have been repaired, a program of more detailed reconnaissance and rock chip sampling over the electromagnetic anomaly will be carried out to identify potential drill targets. The explorer plans to drill the main targets in the 2023 field season once all required approvals are met.
The greater Panorama project consists of three tenements covering 252.3 square kilometres about 40km west of Marble Bar. The western side of the project is located over a complex structural area on the eastern edge of the Shelley monzogranite complex that also hosts the nearby Sulphur Springs and Kangaroo Caves projects. Sulphur Springs holds 17.4 million tonnes at 1.3 per cent copper, 4.2 per cent zinc and 17 grams per tonne silver whilst the Kangaroo Caves deposit hosts 3.55 million tonnes at 6 per cent zinc 0.77 per cent copper and 15.2 g/t silver.
The latest licence extension is the third tenement in the past six months to be granted a further five years of exploration at the Panorama project where Infinity has completed a significant body of work including an initial stream sediment sampling program in 2018. Multi-element assays were received confirming several anomalous sediment values of up to 113 parts per billion gold in the north-west of the site.
A drone magnetic survey was completed in August to aid interpretation of the underlying basement rock and plan further exploration.
Infinity obviously has high hopes for Panorama and now has significant time to explore a number of its key tenements after being granted its extensions.
