Shares in resource investor Metal Tiger PLC (LON:MTL) added over 8% as it increased its holding in Australia-focused Greatland Gold plc (LON:GGP).
Metal now holds 9.56% of Greatland's capital, having bought a further 6mln shares at 0.174p.
Earlier this week, Greatland reported anomalous levels of metal typical of a polymetallic VMS-type system at its Bromus project in Western Australia.
Notable grades of silver, zinc, cadmium and sulphur were unearthed with low level nickel intercepts as well.
Metal's chief executive Paul Johnson said today: "Metal Tiger has noted the decline in the share price of Greatland Gold and reflecting what we consider to be an oversold situation have increased our position accordingly.
"We consider Greatland Gold to have multiple opportunities for considerable value generation for shareholders both in respect of existing projects and any new ventures with which the company may seek to engage."
Separately, it said that its partner in Botswana MOD Resources (ASX:MOD) entered a trading halt on the Australian stock exchange, pending the release of a maiden JORC resource for the T3 target in the Kalahari copper belt.
