Alto Metals Ltd’s (ASX:AME) sampling has extended a gold-in-soil anomaly at the Hancocks prospect within its Sandstone Gold Project in Western Australia to more than 8 square kilometres.
A total of 478 soil samples gathered across the anomaly assayed at over 15ppb, with 93 of the samples returning results greater than 30ppb.
Follow-up drone surveying and mapping will be conducted to delineate specific drill targets at the project in the East Murchison Mineral Field, about 600 kilometres north of Perth

Alto’s managing director Dermot Ryan said: “The systematic approach being applied at Sandstone is potentially outlining new large gold systems.
“This includes detailed magnetic surveys to ‘look through’ lateritic cover, interpretation to identify favourable fractured iron-rich host rocks, and follow-up soil sampling.”
Hancocks sits south of the historic Bull Oak open pits, where the base of oxidation was at a depth of around 50 metres.
The Hancocks area’s most common style of mineralisation is vein quartz within dolerite, basalt, banded iron formations and granite.
Program to “fill in the gaps”
Alto began the soil sampling program in early April, targeting 17 prospective areas across the project licence to fill the gaps in knowledge regarding the area’s geology.
The company had earlier assessed a patchwork of soil sampling results from previous explorers.
Alto’s goal is the delineation of a plus-1 million ounce mineral resource to re-establish standalone oxide and primary gold mining and milling operations.
