The Australian gold exploration landscape has produced fresh momentum, driven by recent results from two ASX-listed explorers. On one front, Gorilla Gold has released new drilling and soil-sampling data at its Mulwarrie Project, reporting high-grade intercepts and expanded surface anomalies. On another, Riversgold continues to hold and advance multiple licences across the Eastern Goldfields and South Australia, maintaining a portfolio that includes the Kurnalpi Project. These developments reinforce why systematic exploration remains a primary method to unlock buried deposits in well-endowed terranes.
The updates combine technical intercepts, surface geochemistry and strategic program planning. For readers tracking project scale and resource growth potential, the interplay between deep drilling results and new soil anomalies provides a practical view of how targets evolve from concept to prioritized drill holes. Below we unpack the Mulwarrie findings announced on 18 March, 2026, summarize Riversgold’s ground position, and consider likely next steps for both companies.

Mulwarrie: high-grade drill results and expanding anomalies
Gorilla Gold’s release on 18 March, 2026 described multiple significant intercepts that lie outside the current mineral resource estimate (MRE). The company reports that recent holes intersected strong gold mineralisation more than 700 metres southeast of the existing MRE, which is currently 350,000 ounces at 3.6 grams per tonne gold. Notable assays include 3.4m @ 9g/t gold from 376.9m and 0.7m @ 24.8g/t gold from 110.3m; these two intercepts are approximately 700 metres apart along strike and sit about 100 metres apart in dip position. Such results underline the potential for continuity beyond the defined resource envelope and revive the geological model for deeper and along-strike exploration.
Drilling specifics and geological implications
The highlighted intercepts suggest discrete, high-grade shoots within a broader mineralised corridor. From a technical perspective, the reported grades and depths indicate both near-surface and deeper mineralisation that may be amenable to different development approaches pending further drilling and metallurgical work. Management has emphasized that these hits are meaningful because they occur outside the current MRE footprint, prompting program adjustments. The company has a large-scale drilling program active—150,000 metres in total—with approximately 55,000 metres focused specifically at Mulwarrie, intended to grow the resource base and increase geological confidence.
Soil anomalies and district-scale footprint
Complementing the drill data, Gorilla’s soil sampling has defined an extensive gold-in-soil anomaly system, including a 2.5-kilometre trend southwest of the MRE and a more than 11-kilometre strike of anomalies 12 kilometres north at Mulline that remain untested. Management describes the combined soil and drilling results as evidence of a district-scale corridor with multiple walk-up drill targets. The company also referenced strategic consolidation with Hamelin Gold and noted prior exploration success, including the addition of more than 1.3 million ounces at an average grade of 3.7g/t during 2026, as part of its growth narrative.
Riversgold: tenure and focus
Riversgold is an Australian explorer concentrating on both gold and lithium opportunities across Western Australia and South Australia. Its assets include the Kurnalpi Project, which comprises ten Exploration Licences and one Application. The company’s strategy is to advance multiple prospects within the Eastern Goldfields, leveraging regional infrastructure and targeted work programs to define drill targets. While Riversgold’s public updates in the referenced feed are concise, the tenure and project mix position the company to participate in any uplift in regional exploration activity prompted by neighbouring positive results.
Implications for explorers and next steps
Collectively, these announcements highlight common themes in early-stage and advanced exploration: the value of systematic soil grids to reveal new trends, the importance of step-out and deeper drilling to test continuity, and the role of consolidation in assembling prospective ground. For investors and stakeholders, the critical items to watch are further infill and step-out assays, updated resource calculations if applicable, and permitting or metallurgical studies that signal a pathway to development. Gorilla’s ongoing work—drilling, studies and permitting—aims to de-risk projects, while Riversgold’s Kurnalpi tenure offers optionality should follow-up campaigns be funded.
In summary, the combination of high-grade intercepts at Mulwarrie and Riversgold’s sustained tenure in the Eastern Goldfields underscores the potential for additional discoveries in the region. Continued drilling, tight integration of geochemistry and geology, and disciplined permitting and development planning will determine whether these early signals translate into expanded resources and, ultimately, mineable assets.
