Gold developers have spent much of the past year riding record prices and renewed investor appetite for large-scale Australian projects. But in a market increasingly crowded with exploration stories, scale, permitting progress and development optionality are starting to matter more.
That backdrop is helping reshape the story around Pilbara Gold Ltd (ASX:PGL), formerly Kairos Minerals Ltd (ASX:KAI, OTCQB:KAIFF, FRA:YAJ), which has spent the past several years steadily building the Mt York gold project in Western Australia’s Pilbara region into a resource now exceeding 2 million ounces (Moz).
Mt York Gold Project
The company’s recent rebrand reflects more than a cosmetic shift. Pilbara Gold is increasingly positioning itself as a gold-focused developer rather than a broad-based explorer, with management now pushing Mt York towards pre-feasibility while simultaneously drilling for further resource growth across the wider district.
At the centre of that transition sits a newly updated 2.1Moz JORC mineral resource estimate, a substantial increase from the previous resource and one management believes still understates the broader scale potential emerging across the project.
2026 Mineral Resource Estimate (MRE)
Mt York starts to look like a serious development asset
Mt York lies about 100 kilometres south of Port Hedland in a region better known globally for iron ore than large-scale gold development. But Pilbara Gold argues the project now combines several features increasingly valued by investors and potential strategic partners: size, location, metallurgy and permitting momentum.
The updated mineral resource totals 61.7 million tonnes grading 1.05g/t gold for 2.082 million ounces, including 1.38Moz in the Indicated category and 703,000 ounces Inferred.
2026 MRE – By Resource Category
Importantly, the company says the resource grew by nearly 700,000 ounces compared with the 2023 estimate while also improving overall grade by about 5%, with higher-grade zones becoming better defined through additional drilling.
2026 MRE – By Grade
Rather than comprising several disconnected deposits, Mt York is increasingly being interpreted as one large mineralised system extending across more than 4.2 kilometres. The project incorporates the Main Hill, Breccia Hill and Gossan Hill zones, with mineralisation remaining open at depth across much of the system.
That scale is becoming central to the investment case.
Pilbara Gold is envisaging a single large open pit operation, supported by what it describes as relatively straightforward metallurgy using a conventional carbon-in-leach processing route.

The company also already holds a granted mining lease and has secured a Native Title agreement with the Nyamal Aboriginal Corporation — the kind of milestones that can often take years for Australian gold developers to achieve.
Drilling campaign targets next phase of growth
While the 2.1Moz milestone marked an important step, management appears focused on demonstrating that Mt York may still be in the earlier stages of its overall growth curve.
Pilbara Gold currently has roughly 50,000 metres of drilling under way across the project, targeting both resource conversion and deeper extensions beneath existing mineralisation.
Cross-sections show multiple zones remaining open at depth beneath the current resource shell, particularly below Main Hill and Breccia Hill.
Mt York – 4.2km Long, Open at Depth
The company is targeting another resource update in the second half of calendar 2026.
Several recent drill intersections continue to reinforce the continuity and scale of mineralisation across the Mt York system, including:
- 36m at 2.00 g/t gold from 4m, 51m at 2.42 g/t gold from 54m and 44m at 1.41 g/t gold from 110m (Main Hill)
- 10m at 4.90 g/t gold from 257m, including 7m at 6.02 g/t (Breccia Hill)
- 11m at 6.97 g/t gold from 112m (Gossan Hill)
The broader geology also appears to support the possibility of a much larger district-scale gold system.
Mt York is hosted within banded iron formation units — a style of mineralisation that has historically underpinned several major Western Australian gold camps. Pilbara Gold says the mineralised corridor reaches up to 100 metres wide in places.
More than just Mt York
While Mt York dominates the current narrative, Pilbara Gold has also been steadily consolidating additional ground around the project.
The company now controls or has applications covering about 535 square kilometres across the broader district, targeting both gold and silver opportunities adjacent to the existing resource.
Management describes the strategy as having effectively “tied up the belt”, with several satellite targets already generating encouraging historical results.
Gold (and Silver) Potential next to Mt York
Among them is the Carlindi prospect, where historical drilling returned intercepts including:
- 6m at 9.1 g/t gold;
- 4m at 10.2 g/t gold; and
- 16m at 1.7 g/t gold.
The nearby Valley of the Gossans prospect has also delivered notable silver results, including 34 metres grading 99.8 g/t silver.
Drilling across several of these satellite targets is continuing through 2026 as the company assesses whether additional deposits could ultimately supplement a future Mt York mining operation.

Outside the Pilbara, Pilbara Gold also retains the Roe Hills project near Kalgoorlie, where management says a maiden mineral resource estimate is anticipated during 2026.
Rebrand signals broader shift in strategy
The transition from Kairos Minerals to Pilbara Gold earlier this year was pitched partly as an effort to better align the company’s identity with its flagship asset and evolving strategy.
But the rebrand also reflects a broader repositioning under way inside the company itself.
Pilbara Gold increasingly appears to be moving away from the earlier-stage exploration profile that defined much of its history and towards a more development-oriented structure. The company has flagged plans to continue refocusing its board and management team as Mt York advances through pre-feasibility and towards potential development decisions.
The balance sheet provides some flexibility to pursue that transition.
Pilbara Gold’s cash position sits at about $35 million, which management says leaves no immediate need for equity dilution while major drilling and study programs continue.
The company has also attracted a growing institutional and strategic shareholder base, including Chinese gold producer Zhaojin Mining, Franklin Templeton and Canadian mining investor Eric Sprott.
Valuation gap becomes part of the argument
Pilbara Gold argues that Mt York still trades at a significant discount to comparable Australian gold developers despite its expanding resource base and advancing development profile.
Using enterprise-value-per-resource-ounce metrics, the company argues PGL currently trades at roughly A$60 per ounce, below several peer developers holding similarly sized Australian gold projects.
PGL compares Mt York against projects held by groups including Minerals260, Ausgold and Saturn Metals, many of which trade at materially higher EV-to-resource multiples.
Peer Comparison
Closing that valuation gap will likely depend on how successfully Pilbara Gold can turn Mt York’s growing resource base into a realistic development pathway, meaning the next 12 months may prove particularly important.
Another resource update, continued drilling success, pre-feasibility progress and permitting advancement are all expected across 2026.
And in a gold market increasingly rewarding scale and development readiness, Pilbara Gold is now trying to demonstrate that Mt York may be evolving into something larger than a typical exploration story.
