Newcrest rose this week because the company released a report outlining the potential for additional mining at its Cadia Valley operations in Australia. The report suggests there are opportunities to increase mining rates and extend mine life, which could result in significant additional gold and copper production. Additionally, Newcrest and Newmont are set to engage in talks regarding Newmont's 32.5% stake in the Cadia Valley operations, which could potentially lead to Newmont increasing its ownership stake. This news has generated positive investor sentiment, leading to an increase in Newcrest's share price. 4. $Northern Star Resources(NST.AU)$ - reaffirmed its full-year guidance Northern Star Resources' share price rose this week despite a six-week setback at its Pogo gold mine in Alaska. This is because the company has reaffirmed its full-year guidance, and investors are taking this as a positive sign. The Pogo mine produced 268,000 ounces of gold in the last financial year, representing about 17% of Northern Star's total gold production. However, the company's management stated that the damage to the ball mill was not significant and that it was confident that the mine would be able to resume production within six weeks. Additionally, the management reaffirmed its full-year guidance despite the Pogo incident. The company's FY23 gold production guidance ranges between 1.6 million and 1.8 million ounces. Northern Star is continuing to work on developing new mines and expanding its operations, which has helped to support investor confidence. Additionally, the price of gold has been rising, which has also had a positive impact on the company's share price. Overall, the market appears to be optimistic about Northern Star's ability to navigate the challenges it is facing and continue delivering strong results.
