Program advancing rapidly, ahead of schedule and under budget

HIGHLIGHTS

• Reverse circulation (RC) upgrade drilling on high value ‘Starter Pits’ ahead of schedule, 2/3 complete¹

• First assays from highest value ‘Stage 1′ area anticipated to be received during the coming weeks¹

ADELAIDE, AU / ACCESS Newswire / October 28, 2025 / Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) ( Barton or Company ) is pleased to confirm that upgrade drilling for the ‘Starter Pits’ at its South Australian Tunkillia Gold Project ( Tunkillia ) is progressing ahead of schedule and under budget, with approximately 2/3 of the current ~18,000m program now complete.

Assuming revenues based upon a gold price of AUD $5,000 / ounce, the ‘Stage 1′ and ‘Stage 2′ optimised open pit areas are modelled to yield 365koz Au and A$1.3bn operating profit during Tunkillia’s first ~2.5 years alone. ¹ Estimated ‘Starter Pits’ cash flows are modelled to repay development more than 2x over during the first year of operations, and more than 3x over during the first 2 years, offering an attractive credit financing profile. ¹

This initial round of drilling is therefore designed to convert these two pit areas to JORC (2012) ‘Measured’ and ‘Indicated’ categories, reinforce modelling confidence and support expedited project financing discussions. ¹

Commenting on Tunkillia’s upgrade drilling programs, Barton Managing Director Alex Scanlon said :

“We are pleased to confirm that the first phase of Tunkillia upgrade drilling is progressing well, ahead of schedule and under budget, with contractors Raglan Drilling consistently delivering an average of over 300 metres drilling per day.

“Prior drilling in the ‘Starter Pits’ area has typically returned Tunkillia’s highest grades. Our modelling that indicates that these pits can deliver a payback period of less than 1 year in operations, offering a very attractive credit profile.”

Program background

Figure 2 shows Tunkillia’s key ‘Stage 1′ and ‘Stage 2′ optimised pit outlines, with the location of planned new drill hole collars (black dots) and completed drill holes (green dots) for the initial ~18,000m drilling program. The program is targeting the upgrade of all ‘Stage 1′ and ‘Stage 2′ mineralisation to JORC ‘Indicated’ category, with the highest value subset of ‘Stage 1′ mineralisation upgraded to JORC ‘Measured’ category. Previous drilling in the highest value ‘Stage1′ area by Barton and others has yielded assays such as 10m @ 15.7 g/t Au from 54m, 9m @ 6.57 g/t Au from 72m, 17m @ 5.90 g/t Au from 79m, and 15m @ 7.64 g/t Au from 100m depth. ¹

The current drilling program is advancing ahead of schedule and under budget, with a total ~12,000m drilling completed across a total 37 days’ drilling, for an average of approximately 325m per day. A first batch of drilling assays from the central highest value ‘Stage 1′ area is anticipated to be received during the coming weeks.

A 2 ^nd stage RC drilling planned for March to June 2026 will then target conversion of all other Tunkillia OSS mineralisation to JORC ‘Indicated’ category. Concurrent diamond drilling ( DD ) will infill and expand Tunkillia’s geotechnical and metallurgical databases to support further pit design optimisation and feasibility studies.

Approximately 2 billion people – one quarter of humanity – now live in regions experiencing moderate to severe increases in seasonality

LONDON, GB / ACCESS Newswire / October 29, 2025 / New research from the Institute for Economics & Peace reveals that changing rainfall patterns are significantly amplifying conflict risks worldwide. The 2025 Ecological Threat Report (ETR), released today, finds conflict death rates are substantially higher in areas where rainfall is concentrating into fewer months, compared to regions where rain is spreading more evenly throughout the year.

Key Findings

• On average in areas where wet and dry seasons are becoming more extreme, there are four times as many conflict deaths as areas where it has decreased.

• In 2024, natural hazards triggered 45 million short-term internal displacements across 163 countries, the highest figure since at least 2008.

• Western Brazil, including parts of the Amazon, has recorded some of the world’s sharpest increases in ecological threat levels. Temperatures have risen at twice the global rate, triggering drought and wildfires.

• Sub-Saharan Africa faces the world’s most severe ecological pressures, with Niger registering the worst ETR score.

• Central and Western Europe recorded substantial overall improvements, in part representing a return to normalcy following Europe’s unusually dry climatic conditions in 2019.

• Despite fears of looming water wars, there have been no interstate conflicts fought exclusively over water in the modern era. In the second half of the 20^th century, at least 157 international freshwater treaties have been signed, offering models for interstate cooperation.

• This cooperative approach to water somewhat mirrors nuclear deterrence since the Second World War. In both cases, the very threat of catastrophic destruction has created pragmatic cooperation. The destruction of water supply can lead to societal collapse.

Approximately 2 billion people – one quarter of humanity – now live in regions experiencing moderate to severe increases in seasonality. This is where wet seasons are becoming shorter and more intense, while dry seasons are longer and drier. These changes are disrupting agricultural calendars and heightening uncertainty for billions of people who rely on seasonal rains for food and livelihoods.

The Ecological Threat Report, produced by the Institute for Economics & Peace, covers 3,125 sub-national areas in 172 countries and territories representing more than 99% of the world’s population. Between 2019 and 2024, ETR scores deteriorated in 96 countries and improved in 74.

Sub-Saharan Africa Approaching Multiple Critical Tipping Points

In sub-Saharan Africa, conflict risk rises sharply when seasonality combines with rapid population growth. Unpredictable rains trigger agricultural stress. When coupled with demographic pressure, competition over land, water and food intensifies. In regions with weak governance and unresolved grievances, this combination proves combustible.

The Karamoja Cluster in East Africa illustrates this pattern. While total rainfall remains relatively stable, its timing has become less predictable, amplifying both drought and flood hazards, leading to increased conflict. With only 2% of cultivated land irrigated compared to a global average of 20%, East African communities remain highly vulnerable to these shocks. Since 2019, increased rainfall seasonality has coincided with a resurgence of pastoralist violence after years of relative peace.

“Rainfall seasonality is becoming a powerful conflict catalyst,”said Steve Killelea AM, Founder & Executive Chairman of the Institute for Economics & Peace.“Where rains are increasingly concentrated into fewer months, conflict deaths rise sharply. In sub-Saharan Africa, rapid population growth amplifies this effect, turning unpredictable seasons into competition for land, water and food. The issue isn’t water scarcity – it’s our failure to capture and distribute it. Only 2% of Sub-Saharan African farmland is irrigated, compared to 20% globally.”

Water Inequality and the Infrastructure Gap

The world’s renewable freshwater supply is finite and increasingly unevenly distributed. There are 295 subnational areas facing very high water risk and another 780 with high risk, affecting nearly 1.9 billion people.

High-income countries have reduced per capita water use by roughly one-third since 2000 through efficiency gains and slower population growth, while many low-income nations face rising total withdrawals and falling per capita availability as populations outpace supply.

Sub-Saharan Africa highlights this imbalance. Per capita water use has dropped from 113 cubic metres in 2000 to just 89 in 2022 – less than one-fifth of the global average. The result is mounting pressure on limited water sources and intensifying competition among farms, industries and households, heightening the risk of conflict.

The failure to capture and distribute water is most acute in sub-Saharan Africa, which has the lowest irrigation rates in the world. To irrigate 34 million hectares would require only 6% of the region’s annual renewable water resources.

Steve Killelea said: “COP30 must prioritise investment in climate-resilient water systems as a foundation for sustainability and peace. Just as nuclear treaties reduced the risk of annihilation, international cooperation on water can reduce the risk of ecological collapse. Both demonstrate that survival depends less on dominance, than on shared responsibility.”

Interstate Water Cooperation

Popular narratives have warned of looming “water wars”, especially in transboundary river and lake basins. The ETR finds this is not the case. While disputes over shared rivers do occur, no interstate wars have been fought over water in the modern era. This makes the lessons of successful interstate water cooperation even more important. In an era of increasing conflict, understanding why interstate cooperation has been so successful can provide a blueprint for avoiding future conflicts.

Even in tense basins such as the Indus River – shared by India and Pakistan – water-sharing has continued despite repeated episodes of conflict, political confrontations and military tension. Water agreements, by necessity, encourage nations to think beyond immediate political grievances toward long-term survival and shared benefit.

Regional Analysis

Sub-Saharan Africa faces the world’s most severe ecological pressures. However, some southern and eastern African countries, including Lesotho, Rwanda, Eritrea and Eswatini, have improved their ETR scores. More favourable rainfall patterns in these countries resulted in marked reductions in water risk over the past five years.

In contrast, northwest Africa has seen the steepest deterioration in ETR scores over the same period, led by Tunisia, Morocco and Algeria, where persistent drought and rising temperatures have reversed the unusually favourable conditions of 2019.

Central and Western Europe recorded notable improvements, marking a return to normal following the extreme dryness of 2019.

“Men’s jewelry is no longer on the sidelines-it’s central to style, culture, and personal storytelling,” said Ankur Daga, Founder & CEO of Angara. “With this launch, we’re not just entering a new category; we’re reshaping it. Angara Man brings colored gemstones, refined craftsmanship, and personalization to a space that has long been defined by metals and logos. It’s jewelry that carries his signature, his narrative.”

Highlights of the collection include:

• Modern Signets & Bands – sculptural forms designed as both everyday essentials and future heirlooms.

• Medallions & Tag Pendants – versatile designs that layer seamlessly or stand alone with distinction.

• Bracelets & Cuffs – bold yet refined silhouettes balancing strength and sophistication.

• New Gemstones – tiger’s eye, onyx, lapis, malachite, turquoise, sapphires, rubies, and more, offered alongside diamonds for striking individuality.

Launching in time for the holiday season, Angara Man makes a confident statement in a fast-growing category – offering versatile designs for the style-conscious man, the statement maker, and the thoughtful gifter.
