GoldArc Delivers Exceptional High-Grade Gold Results as Mining Implementation Plan Takes Shape
GoldArc Resources (ASX:GA8) has delivered outstanding high-grade gold assay results from its recently completed PQ diamond drilling campaign at the Mt Stirling and Stirling Well deposits. The Goldarc Resources Ltd diamond drilling results not only confirm the continuity and quality of mineralisation but provide critical data to finalise the company's mining implementation plan as it transitions from explorer to producer.
The standout intercepts include 5.6m at 8.71 g/t Au from Mt Stirling, with a spectacular high-grade core of 3m at 15.53 g/t Au. At Stirling Well, the drilling returned 1.57m at 14.2 g/t Au, including an exceptional 1m at 30.2 g/t Au.
These results validate the robust nature of GoldArc's 200,000 oz JORC resource base and support the advancement toward production. Furthermore, the exceptional grades demonstrate the potential for continued exploration success across the broader project portfolio.

Exceptional Diamond Drilling Results Confirm Resource Quality
The PQ-diameter diamond drilling campaign, conducted in partnership with BML Ventures, comprised four strategically placed holes totalling 316 metres. The program targeted the core mineralised zones at both Mt Stirling and Stirling Well deposits, delivering results that exceeded expectations.
Moreover, the drilling campaign provides critical geological data to support mine development planning. The systematic approach ensures optimal placement of infrastructure whilst maximising resource recovery.

"These high-grade diamond results are a fantastic validation of the continuity and quality of the Mt Stirling and Mt Stirling Well deposits. By securing this PQ core, we are now moving rapidly into the final stages of metallurgical and geotechnical de-risking." – Paul Stephen, Managing Director
Understanding PQ Diamond Drilling: The Critical Path to Production
PQ diamond drilling represents the gold standard for metallurgical and geotechnical data collection in mining projects. Unlike conventional drilling methods, PQ drilling recovers large-diameter core samples that provide comprehensive data about ore behaviour during processing.
In addition, the PQ core enables detailed analysis of mineralogical characteristics that directly impact processing decisions. This comprehensive understanding reduces technical risk and optimises plant design parameters.
Why PQ Core Matters for Investors
• Enables definitive metallurgical testing to optimise processing parameters
• Provides critical geotechnical data for mine design and safety
• Establishes baseline mineralogy and ore composition
• Determines Bond Work Index for crushing and grinding circuit design
• Validates reagent consumption and mineral recovery rates
The Bond Work Index is a standard measure that quantifies how much energy is required to crush and grind ore to specific sizes. This data directly impacts processing costs and plant design decisions, making it essential for economic assessments.
This data represents the final piece of GoldArc's mining implementation puzzle, positioning the company to transition from explorer to producer with confidence. The Goldarc Resources Ltd diamond drilling results provide the technical foundation needed to advance from exploration to development.
Aggressive Multi-Front Exploration Campaign Underway
GoldArc is simultaneously advancing an extensive exploration strategy across multiple fronts, demonstrating the company's commitment to resource expansion whilst advancing toward production. However, the company maintains focus on its flagship Mt Stirling project whilst pursuing broader exploration opportunities.
The comprehensive drilling strategy ensures continuous news flow whilst de-risking the primary development asset. Furthermore, this approach maximises the potential for resource expansion across the entire project portfolio.
Current Drilling Programs
• 34,000m RC Grade Control Program – Currently underway at Mt Stirling deposit for detailed resource definition
• 6,500m RC Drilling Program – Major campaign targeting Orion, Sapphire, Eclipse, Justice, and Euroa deposits
• AC Drilling Program – Following up mineralisation at Whistler prospect and southern extensions of Cosmopolitan and Altona prospects
This multi-pronged approach ensures continuous exploration momentum whilst de-risking the flagship Mt Stirling project for development. The comprehensive drilling strategy aims to expand the existing resource base beyond the current 200,000 oz whilst providing the technical data required for mine development.
Robust 200,000 oz Resource Base Supports Development Strategy
GoldArc's diversified gold portfolio spans the world-class Leonora and Kookynie districts, providing multiple development pathways and exploration upside. For instance, the resource diversity provides operational flexibility and reduces project risk through multiple ore sources.
The strategic location in established mining districts ensures access to existing infrastructure and skilled labour. Additionally, the proximity to established operations provides potential toll treatment opportunities during early production phases.
GoldArc Total JORC Mineral Resources
| Project | Category | Tonnes | Grade (g/t Au) | Ounces |
|---|---|---|---|---|
| Mt Stirling | Indicated | 391,000 | 2.1 | 26,000 |
| Mt Stirling | Inferred | 2,158,000 | 1.6 | 111,000 |
| Stirling Well | Inferred | 198,000 | 2.3 | 15,000 |
| Orion | Inferred | 370,000 | 2.2 | 26,409 |
| Sapphire | Inferred | 320,000 | 2.1 | 21,605 |
| Total | 3,437,000 | 1.82 | 200,014 |
The resource base provides substantial scale for development, with Mt Stirling representing the flagship asset supported by multiple satellite deposits across the portfolio. The presence of 26,000 oz in the Indicated category at Mt Stirling provides a higher-confidence resource that supports near-term development planning.
What Makes the Geological Context So Compelling?
The Goldarc Resources Ltd diamond drilling results confirm distinct geological controls at both deposits that support continued exploration success. At Mt Stirling, gold mineralisation is associated with high-strain deformation zones in altered meta-basalt rocks.
The gold appears preferentially concentrated in silica-rich zones with elevated arsenic content, creating predictable exploration targets. This geological understanding enables systematic exploration and reduces the risk of unsuccessful drilling campaigns.
At Stirling Well, gold occurs in quartz structures within granitic rocks. These quartz-muscovite-sulphide systems can reach up to 75cm in thickness and represent the main ore-bearing zones.
This structural control provides clear targeting criteria for future drilling programs. Moreover, the consistent geological controls across both deposits suggest potential for discovering similar mineralisation in other areas of the project.
The geological understanding gained from the recent diamond drilling supports both resource expansion and mine development planning. Consequently, the predictable nature of mineralisation reduces exploration risk and supports systematic resource expansion.
Strategic Investment Thesis: Explorer to Producer Transformation
GoldArc presents a compelling investment opportunity as a company transitioning from exploration to production in one of Australia's premier gold regions. The recent PQ diamond drilling results validate several key investment themes that position the company for significant growth.
However, investors should consider both the opportunities and risks associated with this transition phase. The company's systematic approach to development reduces technical risk whilst maintaining exploration upside.
