TSX: DIAM,OTC:SHGDF

 Star Diamond Corporation (the "Company") (TSX: DIAM,OTC:SHGDF) is pleased to announce the engagement of Misty Clifton Engineering LP (MCLP) and SGS Canada Inc (SGS) for a Pre-Feasibility Study (PFS) on the Star Orion South Diamond Project (the "Project").

The PFS will build on the revised Mineral Resource estimate, which was completed in 2024 and the technical work completed for and since the 2018 Preliminary Economic assessment (PEA). Significant parts of the work completed for the 2018 PEA, including the mining method, process plant design, site layout and infrastructure, can be updated and incorporated into the updated PFS. The consultants have estimated the PFS will be completed during Q4 2026.

MCLP is a majority-Indigenous-owned entity (67%) formed with Kineepik Métis Local and Mistawasis Nêhiyawak, co-owned and operated by Clifton Engineering Group Inc. MCLP has a long history of delivering engineering solutions for the Star and Orion South project sites, completing numerous foundation, groundwater and slope stability assessments in support of the project for more than 15 years. MCLP has a local team of principal level technical experts in hydrogeology, hydrology, rock mechanics and regulatory approvals. MCLP will provide PFS level geotechnical, hydrogeological, tailing management and environmental engineering services in support of the Project.

SGS has been involved with the project for over 20 years and were the lead consultants in the completion of the 2018 PEA. They have an experienced engineering division that can complete all the mine design and civil engineering work. SGS Bateman , a wholly owned subsidiary of SGS, will be updating the process design. They have been a diamond processing plant design and construction company for over 100 years.

SGS will be supported by Takraf GmbH in the application of continuous mining systems for overburden removal. Takraf is one of the world's leading manufacturers of surface mining and heavy haul equipment most recently working with Star Diamond on mine design and equipment selection for the 2018 PEA.

MCLP and SGS will be supported by ACA Howe International, who are responsible for the Mineral Resource, Project QA/QC, exploration history and geological modeling for the Project. Working alongside ACA Howe for the Mineral Resource estimate, is Ravenscroft Mining Advisors. Ravenscroft Mining Advisors will be working with Star Diamonds in-house Diamond Specialist Nelson Karun on diamond price modeling and mitigation of risk in diamond price estimates.

Ewan Mason , Chief Executive Officer and Chair of the Board of the Company, said: "Our technical team has assembled an excellent group of consultants who have extensive prior experience on the Project and we are confident they will apply their expertise in a rigorous way to maximize the economics of the Project."

WPIC: Platinum to Record Third Annual Deficit as Supply Fails to Meet Demand

Platinum is heading for a third consecutive annual deficit in 2025, with the World Platinum Investment Council (WPIC) projecting an 850,000 ounce shortfall as demand continues to outpace weak mine supply.

In its latest Platinum Quarterly, the WPIC states that despite a 22 percent year-on-year decline in demand, a lack of metal is expected to create a supply deficit that's only 13 percent lower than 2024's 968,000 ounce shortfall.

Its call comes amid a price breakout for platinum, which pushed past US$1,450 per ounce in July.

NATO Defense Spending Pledge Puts Spotlight on Platinum Group Metals

NATO’s decision to increase defense spending is casting fresh attention on the strategic role of platinum group metals (PGMs), a suite of critical minerals essential to aerospace and military technologies.

The World Platinum Investment Council (WPIC), in its latest "60 Seconds in Platinum" briefing, noted that sustained growth in defense budgets could translate into higher demand for PGMs, which are already deeply embedded in critical defense and aerospace systems.

In the Hague Summit Declaration issued June 25, 2025, alliance leaders committed to raising defense expenditure to 5 percent of GDP annually by 2035, a significant step up from the longstanding 2 percent guideline.

Shanghai Platinum Week Showcases China’s Dominance in Global PGMs Demand

China is solidifying its position as the primary engine for global platinum demand

Record participation in Shanghai Platinum Week underscores the country’s expanding influence in a market facing a deepening supply deficit. The event, which attracted over 590 delegates from 30 countries, took place at a critical moment — just as the platinum market is tightening and a supply shortfall is deepening through 2029.

The World Platinum Investment Council (WPIC) notes that China now accounts for 64 percent of global demand for platinum bars and coins — up from 11 percent in 2019 — driven largely by investors seeking alternatives to gold.

Platinum Price Update: H1 2025 in Review

Platinum began the year trading between US$900 and US$1,100 per ounce.

While platinum and other platinum-group metals are considered precious metals, they largely trade on demand from the auto sector. Platinum is used as a catalyst to control emissions from internal combustion engine vehicles.

Over the past several years, demand for electric and hybrid vehicles has increased, which has led to a reduction in platinum loadouts and lowered overall demand. However, with changing environmental regulations, an end to electric vehicle (EV) mandates and tax credits, the market may be experiencing a turnaround in H1.

Editor's Picks: Platinum Hits 11 Year High, Expert Touts Silver's Bullish Future

It was a week of downward momentum for the gold price.

The yellow metal neared the US$3,400 per ounce level on Monday (June 23) as investors reacted to the weekend's escalation in tensions in the Middle East, but sank to just above US$3,300 the next day.

The decline came as US President Donald Trump announced that Israel and Iran had agreed to a ceasefire. While the ceasefire has not gone entirely smoothly, with Trump expressing displeasure about violations, the news appeared to calm investors.

Platinum Price Surges to 11 Year High, Breaks US$1,400

The platinum price surged above US$1,400 per ounce during Thursday (June 26) morning trading, reaching its highest level in 11 years amid a wave of speculative buying in the US and China.

In the US, industrial demand for the metal is rising as American carmakers scale back their electrification plans. At the same time, new policies are set to walk back consumer subsidies for electric vehicles.

These Trump administration mandates are expected to result in increased demand for traditional internal combustion engines or hybrid vehicles, which require higher platinum loadouts.
