In this week’s Rockets and Tanks, a range of mining companies saw the highs and lows on the Australian Securities Exchange (ASX) yesterday (13 August).
One company trading higher was Bayan Mining and Minerals (ASX:BMM), where its value jumped 39.53% to a share price of $0.12 after updating the market on the progress of the group’s projects in North America.
Projects discussed include the Desert Star and Desert Star North projects, both in California, as well as the Bayan Springs South Project in Nevada, and the Arrel Lithium Project in Québec.
Bayan is currently undergoing exploration programs at the Desert Star projects, after completing a second phase of fieldwork at Bayan Springs South.
The company was required to respond to the ASX’s price and volume query, unaware of any unannounced information that could justify its jump in the market, aside from a current assessment of assays from the Arrel Lithium Project, which remains confidential within Bayan’s reach.
Bayan indicates that recent trading may be a reflection of Dateline Resources’ (ASX:DTR) recent announcement relating to its Colosseum Project, located in close proximity to Desert Star.
