Hawthorn Resources Limited (ASX:HAW) is an Australian mineral exploration company with interests in gold, lithium, copper and other mineral projects across Western Australia. Its principal gold development asset is the Anglo Saxon Gold Project within the Pinjin area, approximately 140 kilometres northeast of Kalgoorlie. On 27 August 2026, Hawthorn Resources Limited (ASX:HAW) announced the commencement of aircore drilling at its Pinjin East prospect, targeting a historical gold-in-soil anomaly that had received limited systematic drilling. The programme represents an additional exploration initiative alongside the company's ongoing evaluation of the Anglo Saxon Mineral Resource and potential future mining activities.

What Does the Start of Aircore Drilling at Pinjin East Mean?

Hawthorn Resources Limited (ASX:HAW) commenced its maiden systematic aircore drilling programme at Pinjin East to investigate a substantial gold-in-soil anomaly identified through historical exploration. The programme comprises 25 planned drill holes covering up to 2,000 metres, with individual holes expected to reach approximately 100 metres or terminate earlier where drilling conditions prevent further penetration.

The target is located within exploration tenement E31/1050 and forms part of the broader Anglo Saxon gold exploration area. The drilling is designed to investigate the regolith profile and underlying bedrock to determine whether the surface geochemical anomaly is associated with primary gold mineralisation.

Aircore drilling provides geological samples from relatively shallow depths and is commonly used to identify prospective mineralised structures before more detailed exploration. The results will help Hawthorn Resources Limited (ASX:HAW) determine whether further reverse-circulation or diamond drilling is warranted at Pinjin East.

What Does the 800-Metre Gold-in-Soil Anomaly Indicate?

The Pinjin East prospect contains a historical gold-in-soil anomaly extending more than 800 metres, with reported gold concentrations exceeding 50 parts per billion across portions of the interpreted trend. The highest recorded soil result reached approximately 10,900 parts per billion, equivalent to 10.9 grams per tonne gold.

These measurements indicate elevated gold concentrations within surface samples, but they do not independently establish a mineral deposit. Soil geochemical anomalies can reflect underlying mineralisation, transported material or other geological processes, making drilling necessary to understand their origin.

The planned aircore programme will investigate whether the geochemical anomaly corresponds with gold-bearing structures within the underlying bedrock. Geological logging and laboratory analysis will also help determine whether mineralisation follows a consistent structural trend.

If drilling identifies bedrock gold mineralisation, the company may consider additional drilling to investigate continuity along strike and at depth. However, the prospect remains at an early exploration stage, and its potential economic significance has not been established.

How Does Pinjin East Fit Within the Anglo Saxon Gold Project?

Pinjin East forms part of Hawthorn Resources Limited's (ASX:HAW) broader gold exploration portfolio in the South Laverton Tectonic Zone of Western Australia. The nearby Anglo Saxon deposit is held through the Trouser Legs Mining Joint Venture, in which Hawthorn has a 70% interest and GEL Resources Pty Ltd holds the remaining 30%.

Hawthorn acts as manager of the joint venture and is responsible for coordinating exploration and development activities. The Anglo Saxon project contains a historically mined open pit and surrounding exploration areas where the company has undertaken drilling to assess potential resource extensions.

The Pinjin East programme provides an opportunity to investigate additional gold targets beyond the currently defined Anglo Saxon deposit. However, geological continuity between Pinjin East and the existing Mineral Resource has not been established.

The results will therefore be evaluated separately from the existing resource until sufficient geological evidence supports a more comprehensive interpretation.

What Does the Updated Anglo Saxon Mineral Resource Show?

Hawthorn Resources Limited (ASX:HAW) announced an updated JORC 2012 Mineral Resource estimate for the Anglo Saxon Gold Project in January 2026, incorporating historical drilling information and results from more recent exploration programmes.

At a cut-off grade of 0.5 grams per tonne gold, the resource comprises approximately 1.53 million tonnes grading 4.06 grams per tonne, containing 199,719 ounces of gold. This includes an Indicated Resource of 703,278 tonnes grading 5.21 grams per tonne for 117,884 ounces and an Inferred Resource of 826,195 tonnes grading 3.08 grams per tonne for 81,835 ounces.

At a higher cut-off grade of 3.0 grams per tonne, the same resource model contains approximately 709,016 tonnes grading 6.64 grams per tonne, equivalent to 151,359 ounces of gold. These figures represent alternative reporting thresholds rather than separate resources that can be added together.

The updated estimate provides geological information for evaluating potential open-pit and underground mining scenarios, although additional technical studies and approvals are necessary before any mining restart.

How Could the Anglo Saxon Resource Support Future Mining?

Hawthorn Resources Limited (ASX:HAW) has been assessing potential development scenarios at Anglo Saxon following completion of the January 2026 resource update. The company previously completed a 53-hole reverse-circulation drilling programme covering approximately 7,856 metres, which provided additional information about mineralisation continuity and the geological characteristics of the existing deposit.

The updated resource estimate has been incorporated into pit optimisation work designed to evaluate potential open-pit mining configurations under revised cost and gold price assumptions. Hawthorn has also been reviewing Stage 2 scoping study outcomes to assess the technical and financial requirements associated with a possible restart.

Any commencement of open-pit mining remains dependent on approval of the required Mine Development and Closure Plan. The project must also demonstrate that its proposed mining and processing arrangements are economically viable under applicable operating conditions.

Although Anglo Saxon has an established Mineral Resource, no new mining decision has been announced.

What Role Could Existing Gold Stockpiles Play?

The Anglo Saxon project contains approximately 80,000 tonnes of low-grade stockpiled material on the historical run-of-mine pad, with an estimated average grade of approximately 1.25 grams per tonne gold. This material represents roughly 3,000 ounces of contained gold based on the company's reported estimates.

Hawthorn Resources Limited (ASX:HAW) has previously considered opportunities to process this material through regional gold treatment facilities. Such an arrangement could potentially provide cash receipts without requiring the company to construct a new processing plant at Anglo Saxon.

However, the commercial viability of stockpile processing depends on metallurgical recovery, transportation expenses, treatment charges, gold prices and the terms offered by potential processing counterparties.

The company has not announced a binding processing agreement or confirmed commercial production from these stockpiles. Any future revenue contribution would therefore depend on completing the required technical and commercial assessments.

How Has Hawthorn's Position at Mt Bevan Changed?

Beyond its gold exploration activities, Hawthorn Resources Limited (ASX:HAW) maintains exposure to the Mt Bevan Project in Western Australia. The project includes magnetite iron ore resources and exploration opportunities involving lithium, copper and nickel.

During the June 2026 quarter, Hawthorn converted its 19.6% equity interest in the Mt Bevan magnetite joint venture into a 1% free-on-board production royalty. The arrangement changes the company's economic exposure to the magnetite project by replacing its direct ownership interest with a potential future royalty entitlement.

The structure may reduce Hawthorn's exposure to future magnetite development expenditure, although the royalty would depend on qualifying production occurring under the relevant contractual conditions.

Separately, Hawthorn retains a 34% interest in the Mt Bevan Other Minerals Joint Venture. Exploration activities undertaken through this venture have investigated lithium-bearing pegmatite targets, although drilling results reported during 2026 were inconclusive.

What Do Hawthorn Resources Limited's (ASX:HAW) FY26 Financial Results Show?

Hawthorn Resources Limited (ASX:HAW) reported a net loss after tax of AUD 595,755 for FY26, compared with AUD 341,645 in FY25. Revenue declined to approximately AUD 490,015 from AUD 1.11 million in the preceding financial year, reflecting changes in the company's revenue and operating activities.

Cash and cash equivalents stood at approximately AUD 11.05 million at 30 June 2026, compared with AUD 12.59 million at 30 June 2025. The balance included approximately AUD 1.28 million held in a mine rehabilitation fund, meaning not all reported cash was available for unrestricted corporate expenditure.

Total assets reached approximately AUD 14.52 million at the financial year-end, while net assets stood at approximately AUD 12.95 million. The June 2026 quarterly cash flow report recorded net operating cash outflows of approximately AUD 165,000 and exploration expenditure of approximately AUD 133,000.

The quarterly funding calculation indicated approximately 66 quarters of available funding based on the reported operating cash outflow. However, this calculation is a historical measure and does not necessarily represent the duration for which larger drilling or development programmes could be funded.

What Are the Main Exploration and Development Risks?

Hawthorn Resources Limited (ASX:HAW) faces geological uncertainty at Pinjin East because the current programme represents the first systematic drilling test of the historical gold-in-soil anomaly. Elevated surface gold concentrations do not guarantee that economically significant mineralisation will be identified in the underlying bedrock.

The company also faces technical and regulatory requirements at Anglo Saxon, where potential mining activities remain dependent on development studies, approvals and appropriate processing arrangements. Although the project has an established Mineral Resource, its eventual production potential will depend on mining costs, metallurgical performance and economic conditions.

The Mt Bevan portfolio carries separate uncertainties associated with commodity markets, joint venture arrangements and future project development decisions. In addition, gold price movements and exploration expenditure may influence the company's future capital allocation priorities.

What Are the Next Milestones for Hawthorn Resources Limited (ASX:HAW)?

The immediate exploration priority for Hawthorn Resources Limited (ASX:HAW) is completing the Pinjin East aircore drilling programme and analysing the geological and assay results. The findings will help determine whether the identified gold-in-soil anomaly is associated with primary bedrock mineralisation and whether additional reverse-circulation drilling should be considered.

At Anglo Saxon, the company is continuing to review potential development opportunities using the updated Mineral Resource estimate and revised project assumptions. Progress on the Mine Development and Closure Plan will remain important to any future mining restart.

Hawthorn may also continue assessing commercial options for its existing low-grade stockpiles, including potential processing through regional facilities.

Further financial disclosures will provide updated information about exploration expenditure, cash availability and the company's capacity to fund additional programmes. The results from Pinjin East and the outcome of development studies at Anglo Saxon will be central to determining the next stage of its Western Australian gold activities.
