In the red

A review of Carbine Resources (ASX:CRB) was less than glowing for investors this morning, sending the share price down 56 per cent to 3.5c by 12.45pm AEDT.

It told investors the all-in sustaining cost had increased from $594 an ounce to $862 an ounce — up 68 per cent from its initial feasibility study estimates.

Carbine said it was down to higher cyanide consumption and lower by-product credits due to a lower pyrite price.

RXP Services (ASX:RXP) results did little to excite investors despite key acquisitions.

Profits were down 27 per cent at 51c — a result put down to exiting commercially unviable work and a reduction in work with two major clients.

BPS Technology (ASX:BPS) board changes were to blame for its share price slide this morning, down 24 per cent to 37c at 12.45pm AEDT.

It slashed its forecasts almost in half to $2.7 million, down from a previously expected range of $4 million to 4.5 million.

Meanwhile, both the CFO and CEO have resigned leaving gaping holes in its management.

Catapult Group (ASX:CAT)‘s latest results left investors skittish, with shares trading down 19 per cent at $1.31.

It told investors a half-year loss of $14 million (compared to loss of $5 million the same period last year) was in line with expectations.

After a cracker trading day yesterday, NuCoal Resources (ASX:NCR) gave back 22 per cent to trade at 2.8c by 12.45pm AEDT.

It comes after continued dialogue around legal action against the NSW government for seizure of its licences.
