Alto Metals hits more shallow gold at Lords Corridor, updated resource by March
A highlight intercept from latest drilling at Alto Metals’ Sandstone gold project was 15m at 3.1g/t gold from 198m, including 6m at 5.3g/t gold from 205m.
Alto Metals (ASX: AME) has hit more shallow gold at the historic Lord Henry open cut mine in Western Australia, part of the company’s Lords Corridor target at its Sandstone project.
Reverse circulation drilling returned 35m at 2.2 grams per tonne gold from 43m down hole, and 24m at 2.3g/t from 31m, including 4m at 10.9g/t.
Another 50 assays, mainly from the Lord Henry, Vanguard and Indomitable prospects, remain outstanding.
Alto is to begin a gravity survey over the Lords Corridor early next month and preparations are also under way for an induced polarisation (IP) survey.
The Lords Corridor is more than 3km long.
Multiple gold targets along corridor
Alto’s ground contains numerous former open pits, prospects and gold occurrences, including Lord Nelson and Lord Henry, Havilah and Maninga Marley, Ladybird, Indomitable, Tiger Moth, Vanguard and Vanguard North, Oroya & Hacks, Bull Oak, Sandstone North, and Bulchina.
The company’s 900sq km project is on the Sandstone Greenstone Belt, where gold was discovered at the end of the 19th century.
The belt has produced more than 1.3 million ounces of gold from numerous underground and open pit mining operations.
Of this, some 612,000oz was produced between 1994 and 2008 from the open-pit mining of shallow oxide ore by the former Herald Resources and Troy Resources (ASX: TRY).
Drilling focusing on targeting high-grade strike
The company’s Sandstone gold project currently hosts a mineral resource estimate of 6.2Mt at 1.7 g/t gold for a contained 331,000oz.
The 2021 drilling campaign has focused on expanding these resources and targeting further high-grade strike and depth extensions of existing mineralisation.
The planned IP survey will cover an initial 3km of the Vanguard trend.
Alto says the mineral resource update is progressing well and is on track for release by the end of the March quarter next year, subject to further assays pending.
The Lord Henry drilling is designed to target extensions around previous high-grade intersections south of the historic pit, along with step-out drilling to the north.
