Mining also notable: Ramelius starts Eridanus cutback in Australia

Mining Wednesday, November 4, 2026 - Updated Nov 4, 2026 07:17

Ramelius Resources has started the stage 3 open pit cutback at Eridanus in Western Australia, Oman awards the Mazoon copper mining contract to China's Hongda, and Fortuna advances permitting at Diamba Sud in Senegal.

Why it matters: A cutback feeding a 600,000 ounce ambition, a Chinese contractor winning an Omani copper build and a Senegalese gold permit step show where mid tier growth capital is actually moving this week.

Data as of Items published November 3 to 4, 2026. The Ramelius item was corroborated against its ASX outlook documents; the Oman and Fortuna items are reported at headline level from their trade sources in this run and are flagged as such.

Ramelius Resources has commenced the stage 3 open pit cutback at its Eridanus gold deposit in Western Australia, a future ore source for its Mt Magnet processing hub. Eridanus hosts a mineral resource of about 30 million tonnes grading 1.6 grams per tonne for 1.5 million ounces, and the cutback supports the company’s target of 560,000 to 610,000 ounces of group production in the 2030 financial year, alongside a new three million tonne a year circuit at Mt Magnet being built by Primero. Group ore reserves rose 79 percent to 4.3 million ounces in the latest annual update. The September quarter produced 48,839 ounces at an all in sustaining cost of A$2,656 an ounce, with full year guidance held at 205,000 to 225,000 ounces.

Oman’s Minerals Development Oman has awarded the mining contract for the Mazoon Copper Project to China’s Hongda, International Mining reported, a contractor award that moves the sultanate’s flagship copper development toward construction. Terms were not detailed in the reporting available to this run.

Fortuna Mining’s permitting application at the Diamba Sud gold project in Senegal has advanced, Mining Weekly reported, a procedural step for one of West Africa’s more watched development stage gold assets. The stage reached and any conditions were not detailed in the reporting available to this run.

XCMG XDE260 mining trucks are now operating with SimFer at Simandou in Guinea, International Mining reported, a fleet marker for the ramp that Macquarie credits with offsetting iron ore supply cuts elsewhere. Wesdome Gold reported drilling aimed at lower cost production at Eagle River in Ontario, and Collective Mining reported a broad gold intercept at its Apollo project in Colombia, both at headline level in the Northern Miner in this run. Tanzania’s mining sector reforms and investment were the subject of government aligned reporting on allAfrica, context rather than a new measure, with no specific code or royalty change identified.
