The annual Diggers & Dealers Mining Forum in Kalgoorlie, Western Australia, has drawn global resource executives, investors, and analysts to examine the evolving state of the sector. Industry discussions this week underscore a defining theme for gold mining news 2026: major producers are aggressively scaling output and driving down unit costs, while critical minerals and rare earths command unprecedented strategic focus. From Capricorn Metals’ multi-asset trajectory toward 500,000 ounces per annum to Northern Star’s transformative KCGM expansion, gold operators are positioning themselves for sustained operational resilience.
Capricorn Metals Targets “Range 500” Growth Trajectory
Capricorn Metals used its platform at the Kalgoorlie forum to detail its strategic pathway toward becoming a multi-asset gold producer capable of generating approximately 500,000 ounces per year. The company’s growth blueprint centers on the operational maturation of the Karlawinda Gold Project alongside the development of the large-scale Mt Gibson project.
At Karlawinda, processing capacity is actively expanding from 4.0 million tonnes per annum (Mtpa) to 6.5 Mtpa. Company disclosures indicate that this throughput increase will lift annual gold production to a sustained run-rate of approximately 150,000 ounces in the near term. Complementing this, the Mt Gibson project: boasting a resource base of 4.8 million ounces and 3.3 million ounces in reserves: anchors the next phase of expansion. Once commissioned, Mt Gibson is projected to deliver roughly 260,000 ounces per annum over a mine life exceeding 17 years.
By combining Karlawinda and Mt Gibson, Capricorn has established a clear line-of-sight past 400,000 ounces annually, underpinning its corporate “Range 500” target and cementing investor confidence in its Western Australian asset base.
Northern Star Resources Drives Scale at KCGM Hub
Northern Star Resources delivered key updates regarding its flagship Kalgoorlie Consolidated Gold Mines (KCGM) Super Pit operation. The centerpiece of Northern Star’s organic growth strategy is the construction of a new, larger processing plant designed to lift mill throughput from 13 Mtpa to 27 Mtpa.
This more than two-fold increase in processing capacity is expected to materially reduce unit processing costs and solidify KCGM as a long-life cornerstone asset in Northern Star’s portfolio. Industry analysts at the forum noted that the massive scale of the new facility allows for lower-grade ore stockpiles to be economically processed, expanding overall reserve utilization and extending operational visibility across the Goldfields hub.
Minerals 260 Advances Bullabulling Project
In the developer segment, Minerals 260 presented significant advancements at the Bullabulling Gold Project. The project’s mineral resource estimate has expanded to 6.2 million ounces, supported by a maiden ore reserve of 2.5 million ounces and a comprehensive Pre-Feasibility Study (PFS) outlining a post-tax net present value (NPV) of A$2.3 billion and a 43% internal rate of return (IRR).
Initial operations at Bullabulling are planned around a 5 Mtpa processing facility targeting roughly 150,000 ounces of gold per year, with infrastructure modularly sized for an expansion to 7.5 Mtpa. Backed by a A$220 million funding package from Franco-Nevada, Minerals 260 has commenced early site construction: including accommodation village installation and water bore drilling: with first gold production targeted for late 2028.
Rare Earths and Critical Minerals Dominate Forum Talks
Beyond precious metals, the intersection of gold development and critical minerals formed a core pillar of discussion in Kalgoorlie. Ardea Resources updated delegates on the Kalgoorlie Nickel Project’s Goongarrie Hub, which is progressing through its Definitive Feasibility Study (DFS).
The Goongarrie Hub is fully funded up to A$98.5 million by a Japanese consortium comprising Sumitomo Metal Mining and Mitsubishi Corporation, earning up to a 50% joint venture interest upon a final investment decision. Designed to produce approximately 30,000 tonnes of nickel and 2,000 tonnes of cobalt equivalent annually over a 40-year mine life, the project underscores how critical minerals integration is reshaping regional infrastructure financing in Western Australia.
Key Gold and Critical Minerals Project Milestones
| Company | Project | Commodity | Key Milestone / Target | Financial / Capacity Metrics |
|---|---|---|---|---|
| Capricorn Metals | Karlawinda / Mt Gibson | Gold | Expansion to 6.5 Mtpa / Mt Gibson dev. | ~150K oz/y (Karlawinda) + ~260K oz/y (Mt Gibson) |
| Northern Star | KCGM Super Pit | Gold | Mill capacity expansion | 13 Mtpa scaling to 27 Mtpa throughput |
| Minerals 260 | Bullabulling | Gold | PFS completion & early works | 6.2 Moz resource, 2.5 Moz reserve, A$2.3b NPV |

Outlook for Operators and Investors
The proceedings at the Diggers & Dealers Mining Forum 2026 highlight a maturing Australian mining sector focused on disciplined capital allocation, technological scale, and multi-asset diversification. As gold producers navigate rising input costs through plant optimization and high-capacity milling, operators with clear pathways to multi-hundred-thousand-ounce production profiles are well-positioned to capture robust market margins.
