Mt Gibson ramps up as cyclone fizzles

Mount Gibson Iron says its Koolan Island iron ore operation will be back to full capacity today after ex-Tropical Cyclone Magda fizzled out over the weekend.

On Friday, Mount Gibson evacuated more than 200 employees off Koolan Island after the weather bureau issued a cyclone warning.

However, later that day, the cyclone crossed the Kimberley coast near Kuiri Bay and tracked south, weakening as it passed over Koolan Island.

"Mount Gibson is pleased to confirm that no damage was recorded at Koolan Island, with only moderate rainfall recorded," the company said in a statement.

"Mount Gibson commenced re-mobilising 228 employees to Koolan Island over the weekend, with full re-mobilisation to be completed today."

"Mine production will be at full capacity once all employees have returned to site."

Shares in Mount Gibson were up 1.5 cents to $1.595 at 11:52 AEDT.
