- Initial rock-chip grab sampling undertaken within the GMN tenement
- Mainly examining 300m to 600m along strike from Malhada do Angico mine,
- Three samples returned with tungsten (analyses exceeding the upper analytical limit
- Rock sampling also been undertaken within the Malhada do Angico mine tenement
Gold Mountain (ASX: GMN) has secured an exclusive right to acquire a mining application covering approximately 857.53 hectares over the Malhada do Angico tungsten mine, which operated in Brazil during World War II.

The Malhada do Angico mine is adjacent to GMN’s Logradouro tenements within the Seridó tungsten province of northeast Brazil, one of South America’s principal tungsten-producing regions.
GMN is assessing the mining application over the mine and has entered an exclusive 12 month agreement with Emprogeo Mining Business EPP Ltda (EMPG) to conduct due diligence prior to purchase.
“GMN is excited by this tungsten opportunity, which I recently visited. We are fast tracking the exploration program and will commence drilling as soon as the necessary permits are obtained,” executive director, David Evans, said.
“We have also commenced auger drilling of the historical tailings to confirm the grade and obtain samples for metallurgical test work.”
The historical tungsten mine is located only 10 km from Parelhas, a regional hub for mining and agriculture, and from the major wind farm infrastructure adjacent to Parelhas.
The project is also located within the same broad structural and stratigraphic environment as the currently producing Brejuí tungsten mine, approximately 47 km north of GMN’s Logradouro tenements.
Mapping of historical workings and skarn outcrops across the GMN and Malhada do Angico tenements has been undertaken, and a drilling program has been designed and is currently progressing through the permitting process.
\A combined strike length of approximately 2,000m of skarn has been identified within the main mine workings zone, with a further approximately 2,000m of skarn and minor workings identified in the eastern part of the Malhada dos Angicos mine tenement.
The historical Malhada do Angico mine was developed within scheelite-bearing skarn units hosted by the Jucurutu Formation, which is the regional host to numerous scheelite deposits, including the Brejuí Mine, one of Brazil’s largest tungsten mines.
Historical mining by Mineração Fluminense, during World War II, involved the extraction of exposed, primary scheelite-bearing host rocks within the Malhada do Angico workings. The material was processed on site, and GMN is currently drilling the historical tailings to estimate their grade and thickness and to obtain samples for metallurgical test work.
GMN was down 3.33% to 5.8¢. Mkt cap $16.01M.
