Brightstar Resources to Host Investor Webinar on Updated Sandstone Gold Project Mineral Resource Estimate

Brightstar Resources Announces 16 July Webinar on Sandstone Mineral Resource Update

Brightstar Resources Limited confirmed it will host a live online investor briefing on Thursday, 16 July 2026, offering shareholders, investors, and media direct access to management commentary following the recent update of the Mineral Resource Estimate for the Sandstone Gold Project. The session will start at 9:30 am Western Australian Standard Time (11:30 am Australian Eastern Standard Time) and is expected to last approximately 30 minutes. Interested participants must register in advance via the link provided in the company’s update. Questions can be submitted ahead of the webinar by emailing the investor relations contact.

Managing Director Alex Rovira will lead the presentation, providing an overview of the updated Sandstone Mineral Resource Estimate and its role in Brightstar’s strategic plans for the region. Investors and analysts tracking the company’s resource growth will have the opportunity to engage directly with management and ask questions during the live session. Brightstar encourages participation from shareholders, investors, and media as it navigates a critical phase of development across its project portfolio.

Alex Rovira to Detail Sandstone Gold Project’s Role in Brightstar’s Growth Strategy

The webinar will feature Managing Director Alex Rovira explaining how the updated Sandstone Mineral Resource Estimate aligns with Brightstar’s broader sequential development strategy. The company aims to become a leading mid-tier gold miner by developing two flagship projects: the Goldfields Project and the Sandstone Project. The Sandstone Gold Project serves as the second key pillar, and the updated resource estimate marks a significant milestone in advancing this asset toward a clearer development path.

Brightstar’s strategy focuses on leveraging both projects to build a substantial growth platform within Western Australia’s gold sector. By updating the Sandstone Mineral Resource Estimate and communicating its implications directly to investors, Brightstar signals that Sandstone is progressing alongside the near-term Goldfields Hub development. The webinar will offer insights into management’s views on project sequencing and prioritization, especially as the Goldfields Hub approaches its targeted production start date.

Brightstar’s Mineral Resource Base Surpasses 4.5 Million Ounces Across Western Australia

Brightstar Resources holds a significant gold mineral resource portfolio spanning the Goldfields and Sandstone regions in Western Australia, with a combined Mineral Resource base exceeding 4.5 million ounces. These assets are located within a Tier-1 jurisdiction—known for stable regulations, established infrastructure, and a strong mining history—providing Brightstar with a sovereign risk advantage.

The company highlights that its projects benefit from proximity to key infrastructure such as sealed highways and are situated on granted mining leases. The presence of granted leases reduces regulatory uncertainty and supports faster project advancement compared to other developers. These factors position Brightstar’s assets as relatively advanced in terms of infrastructure and tenure, underpinning the company’s readiness for development across both regions.

Goldfields Hub Feasibility Study Projects Over 75,000 Ounces Annually and A$606 Million NPV

While the webinar focuses on the Sandstone update, Brightstar’s broader profile provides essential context. The January 2026 updated Feasibility Study for the Goldfields Hub projects annual gold production exceeding 75,000 ounces over a six-year mine life. Financial highlights include approximately A$1 billion in life-of-mine cashflows, a net present value (NPV) of A$606 million at an 8% discount rate, and an internal rate of return (IRR) of 74%.

These figures suggest that the Goldfields Hub, if developed as planned, could generate substantial returns. Though feasibility outcomes are forward-looking and subject to assumptions about gold prices, costs, and execution, they provide a framework for understanding the potential value embedded in the Goldfields Project and the strategic importance of advancing Sandstone as a complementary growth asset.

Construction Underway for 1.5 Million Tonne Per Annum Processing Plant at Goldfields Hub

Brightstar confirmed construction has commenced on a 1.5 million tonne per annum processing plant as part of the Goldfields Hub development. The company targets gold production commencement in the June quarter of 2027. Achieving this milestone would mark Brightstar’s transition from development-stage to operating gold producer, highlighting operational momentum on the Goldfields side while Sandstone progresses through resource definition.

Processing plant construction is capital-intensive and time-sensitive. Although no specific updates on construction progress or capital expenditure were provided, the confirmation of ongoing work indicates project execution is advancing. Investors should watch for future updates on construction milestones, commissioning timelines, and capital cost adjustments. The June quarter 2027 production target remains a key date for market tracking.

Sandstone Project Progresses Alongside Goldfields Hub in Brightstar’s Mid-Tier Producer Ambition

Brightstar aims to become a leading mid-tier gold miner, typically producing between 100,000 and 500,000 ounces annually. The company’s sequential development plan involves first bringing the Goldfields Project into production to generate cashflow, which could then support the Sandstone Project’s development. The updated Mineral Resource Estimate for Sandstone is a foundational step in defining the asset’s scale and quality, aiding future development planning and financing.

This sequential approach reduces reliance on external capital by potentially self-funding subsequent projects. While no specific financial or timeline details for Sandstone’s development were disclosed in this update, the emphasis on the resource estimate highlights its importance within Brightstar’s growth strategy.

How to Join the 16 July Investor Webinar

Brightstar’s 16 July investor briefing is open to shareholders, investors, and media. Participants must register in advance via the link in the company update. The online format enables attendees from across Australia and internationally to join without traveling to Perth. The session’s 30-minute duration allows Managing Director Alex Rovira to present the updated Sandstone Mineral Resource Estimate and respond to investor questions.

Participants are encouraged to submit questions in advance by emailing the investor relations contact. This allows management to prepare thorough responses and address common investor concerns efficiently during the live briefing. Lucas Robinson serves as Brightstar’s Investor Relations contact and can be reached by phone or email as detailed in the company update. Submitting technical or strategic questions ahead of time is recommended to maximize the session’s value.

Western Australia’s Gold Sector and Brightstar’s Tier-1 Jurisdiction Advantage

Brightstar’s assets are located entirely within Western Australia, a globally recognized premier destination for gold exploration and production. The state hosts Australia’s largest gold producers and benefits from a mature mining services sector, skilled workforce, and stable regulatory environment. Operating in a Tier-1 jurisdiction mitigates country-specific risks such as sovereign uncertainty, infrastructure gaps, and permitting delays, offering Brightstar operational advantages.

The Goldfields and Sandstone regions are historically significant gold-producing areas. Brightstar’s granted mining leases and proximity to sealed highways and existing infrastructure enable the company to advance development plans with operational readiness that many pure explorers lack. Management highlights these locational and tenure strengths as key differentiators compared to peers operating in higher-risk or less-developed regions.

Significance of the Sandstone Mineral Resource Update for Brightstar’s Growth

An updated Mineral Resource Estimate formally quantifies the quantity and grade of mineralisation based on additional drilling, refined geological modelling, or improved estimation methods, complying with the JORC Code. Brightstar’s updated Sandstone estimate reflects ongoing investment in defining this asset’s scale, a critical prerequisite for advancing development studies.

The dedicated investor webinar indicates management views the update as a significant development warranting direct communication with shareholders. Although detailed figures on tonnage, grade, and classification were not included in this announcement, the 16 July 2026 webinar will provide context on the resource update’s implications for Sandstone’s development path. Investors attending will gain management’s strategic perspective on the update.

Risk Factors for Investors Monitoring Brightstar’s Dual Projects

As an emerging gold producer, Brightstar faces risks typical of development-stage companies. The 1.5 million tonne per annum processing plant construction at the Goldfields Hub carries execution risks related to schedule and costs. Delays from weather, supply chain issues, labor shortages, or technical challenges could impact the targeted June quarter 2027 production start. Investors should monitor company updates for any changes to construction timelines or budgets.

Additionally, Brightstar’s financial outcomes will be influenced by gold price volatility driven by global macroeconomic factors beyond its control. The financial metrics in the January 2026 Feasibility Study are based on assumptions that may differ from actual market conditions at production. The Sandstone Project remains in earlier development stages, requiring further studies, permitting, and financing before construction. Investors should review all company disclosures carefully and seek independent financial advice before investing in Brightstar Resources.
