Northern Star shares leap on gold resource boost
Northern Star shares are up 5.3% at time of writing, changing hands for $22.15 apiece.
This strong performance follows the release of the ASX 200 gold stock's mineral resource and reserve estimate update.
Northern Star reported that its total mineral resources increased by 18.2 million ounces of gold to 88.9 million ounces, after mining depletion.
And the Aussie gold miner's ore reserves increased by 6.1 million ounces of gold to 28.4 million ounces.
Northern Star shares also look to be catching investor interest, with the miner revealing that it was able to grow its resource at a low-end discovery cost averaging less than $23 per ounce.
Commenting on the growth, Northern Star managing director Stuart Tonkin said:
For the first time, the Hemi Mineral Resources and Ore Reserves have been reported under the Northern Star methodology and economic framework, establishing a consistent, portfolio-wide approach that enhances comparability and underpins future growth opportunities.
Ampol shares gain on ACCC acquisition greenlight
Ampol is also grabbing investor interest today.
Ampol shares are up 2.5% at $34.63 each after the Aussie fuel supplier announced that the Australian Competition and Consumer Commission (ACCC) has approved Ampol's acquisition of fuel and convenience retailer EG Australia.
The company noted that the approval is conditional on Ampol's divestment of 41 sites. Ampol said it has entered into a binding agreement to sell the 41 sites to Metro Petroleum.
Citing its strong balance sheet, Ampol said it will cash settle the scrip component of the purchase price. The seller of EG Australia will receive a net cash consideration of approximately $1.115 billion.
"This transaction is a major step in delivering Ampol's strategy by strengthening our retail network and enhancing our segmented customer offer," Ampol CEO Matt Halliday said.
Ampol expects to complete the acquisition of EG Australia on 30 June.
