Second-phase drilling proves Indomitable for Alto Metals

Alto Metals has returned positive results from a second phase of drilling at the Indomitable site that forms part of its greater Sandstone gold project, including a 24m hit at 2.2 grams per tonne gold from 160m.

The intercept contained solid sections including 16m going 3g/t gold from 167m, 1m grading 8.8g/t gold from 175m and another 1m hit at an impressive 9.4g/t gold from 182m at the company’s operation in Western Australia’s Mid West region.

Alto is now conducting a 5000m follow-up reverse-circulation (RC) campaign at Indomitable, where it is targeting a depth down to 250m below surface – the deepest drilling at the site to date. The latest results are from the first four holes sunk in the program and the company says it confirms high-grade mineralisation.

The figures were recorded in 1m photon assays relating to four RC holes, comprising 858m at an average downhole depth of less than 200m.

Last month, management released impressive figures from drilling at Indomitable, including 16m at 13.1g/t gold from 19m that included 3m grading 62.2g/t gold from 29m, in addition to a 1m section going an eye-popping 122.6/t gold from 29m.

Whilst very early in the program, and not to be taken out of context, the initial results from these first holes is encouraging and represents the deepest significant gold mineralisation intersected at Indomitable. SRC941 returning 24m @ 2.2 g/t from 160m in oxide, again highlights the significant depth of weathering in the system and the potential for mineralisation in primary rock at depth.

The company’s Sandstone project covers about 900 square kilometres in the East Murchison mineral field, about 600km north of Perth, and comprises the vast majority of the historic Archaean Sandstone Goldfield.

In April, Alto overtook the million-ounce milestone after unveiling a significant increase in shallow gold resources at its wholly-owned Sandstone project.

The company released a mineral resource update for the operation that now boasts 23.5 million tonnes at 1.4g/t gold for 1,046,000 ounces, with the potential for further resource growth along strike and at depth. RC drilling continues at the site and the optimised pit-shell constrained JORC mineral resources estimate is 832,000 ounces of gold with a head grade of 1.5g/t gold.

The upgrade showed the resource at Indomitable has almost tripled to now host 5.4 million tonnes at 1.2g/t gold for 210,000 ounces of the precious yellow metal. The Indomitable gold camp is defined through a more than 3km strike length and sits within about a 20km north-west to south-east-trending gold corridor that also hosts the Vanguard and Havilah deposits.

With drilling continuing and further assays pending, Alto could potentially be on the path to another significant upgrade at its Sandstone project.
