The miner and explorer reported that underlying sales from its Cobre magnetite stockpile in New Mexico were up 26% at £1.1mln and tonnage rose 23% to 12,704 in the three months to the end of September, against last year, thanks to a resumption of demand from its regular customers.
Strategic also received the forfeit of a US$375,000 deposit from its main customer which sent overall revenues 89% higher in the period.
The AIM-listed company is currently pursuing US$21mln plus damages in an arbitration claim against Cobre’s main customer, whose name has not been disclosed.
The bill includes at least US$2.3mln sought in relation to payments still outstanding, and US$19mln for lost profits for the balance of the contract.
In the update, Cobre’ said its revenue for the full year fell to £3.2mln, almost half of the 2018 figure, which Strategic said was due to the adverse impact caused by its major client's diminished purchases.
As recently as July, the client was expressing its intention to make payment.
Strategic’s managing director, John Peters, said: "The progression of a formal claim against the major client at Cobre has resulted in the board having to reconsider the pace at which it can progress planned projects.”
Peters also noted that last quarter’s rallying magnetite sales “augurs well for sales over the coming year”, and that the company remains in funding talks.
The minerals group’s non-restricted cash balance stood at US$760,000.
