Northern Molong Porphyry Project

New South Wales, Australia · Open Pit

Under Development
GoldCopper
Mine life
17 years
Overview
The Northern Molong Porphyry Project is an exploration project and not an operating mine. Alkane Resources is conducting significant exploration activities, including drilling, to grow its understanding of the regional geology and identify new deposits. The project is covered by five exploration licences across 180 square kilometres. Within the broader project, the Boda-Kaiser deposits are being progressed via a scoping study and baseline environmental assessments to evaluate the potential for a long-term, bulk-tonnage mining and processing operation.
Processing
As an exploration project, there is no operational processing plant. However, metallurgical test work has been conducted on deposits within the project area, such as Boda, to estimate potential metal recoveries.
Equipment
Exploration activities utilise diamond core and Reverse Circulation (RC) drill rigs. An Airborne Gravity Gradiometer survey using the FALCON system was flown over the entire project area in late 2023 to image geology to a depth of 500-600 metres. Other field exploration techniques include aeromagnetic and electrical geophysics.

Overview
The Fruta del Norte mine, located in the Cordillera del Cóndor region of southeast Ecuador, is a high-grade, underground gold and silver mine wholly owned and operated by Lundin Gold Inc.
Production
As of December 31, 2024, proven and probable mineral reserves were estimated at 5.54 million ounces of contained gold. In 2024, the mine produced a record 502,029 ounces of gold. Production guidance for 2026 is between 475,000 and 525,000 ounces of gold.
Processing
The processing plant has a current throughput capacity of 5,000 tonnes per day. The processing method involves a gravity-flotation-leach circuit. Ore is first crushed and then undergoes grinding in a semi-autogenous (SAG) and ball mill circuit. Free gold is recovered through a gravity circuit. Following this, a flotation circuit recovers gold associated with sulphides. The tailings from flotation are then processed in a conventional Carbon-in-Leach (CIL) circuit. The plant produces both a gold concentrate and doré.
Equipment
underground mining fleet includes Cat / AD45B haul trucks (45 tonnes capacity). Processing plant equipment includes a jaw crusher, a SAG mill, a ball mill, gravity concentrators, three Jameson flotation cells, and a concentrate filter.
