Brazilian Rare Earths (ASX:BRE) retracted and withdrew the production target for its Rocha da Rocha project in Brazil and all forecasted financial information because the proportion of inferred mineral resources scheduled in the mine plan from year nine to year 14 resulted in a lack of reasonable basis for the forward-looking statements, according to a Tuesday Australian bourse filing.

The underlying Monte Alto and Sulista mineral resource estimates were not retracted, the company said, adding that it instead prepared an integrated Monte Alto and Camaçari case, excluding the Sulista project.

The case projects an after-tax net present value of $6 billion at an 8% discount rate and an after-tax internal rate of return of 90% over a nine-year mine life.

The average annual neodymium-praseodymium oxide production is forecast at 6,351 tonnes in the first five years and 5,661 tonnes over the life of mine, with average annual triuranium octoxide production of 540 tonnes in the first five years and 466 tonnes over the life of mine.

Average annual revenue is forecast at $1.69 billion, with cash operating costs of $214 million and earnings before interest, taxes, depreciation and amortization (EBITDA) of $1.4 billion.

The company's shares fell past 1% in recent trading on Tuesday.
