Altura Mining has sought to draw a line in the sand with the troubled ramp-up of its Pilgangoora lithium project by declaring commercial production.

The Pilbara-focused fledgling miner said it was delivering ore at, or above, grade forecast with a waste-to-ore ratio in line with its mine plan.

Altura Mining Managing Director James Brown said the company would turn its focus to ensuring the mining, processing plant and logistics chain were operating as efficiently as possible.

Altura’s half-year accounts revealed yesterday the company had lost $11 million in the six months to the end of December.

On Tuesday, Altura advised it would double the size of a share purchase plan to $10 million after being “inundated” with interest from shareholders.

The original $5 million placement was announced last month as part of a broader $28 million funding package as the company sought to bolster its balance sheet during a laboured eight month ramp-up of Pilgangoora.
