Crinum operator fined $7m after on-site death
Mastermyne Crinum Operations has been fined $7m after being convicted over the death of underground miner Graham Dawson in 2021 at the Crinum mine in Queensland.The District Court of Queensland sentenced Mastermyne Crinum Operations today after a jury in the District Court at Emerald found the company guilty of industrial manslaughter in March.Mastermyne has lodged a Notice of Appeal, with a hearing date yet to be determined.Resources Safety and Health Queensland (RSHQ) said the case marked the first time an industrial manslaughter charge had been brought under Queensland’s mining safety and health legislation since it came into effect in 2020.Mr Dawson was an experienced underground miner who was killed after the roof of the Crinum mine collapsed and crushed him.It took four days for Mr Dawson’s body to be recovered.At the time of the event, Mastermyne employed and managed the whole production workforce at the Crinum site.A spokesperson RSHQ said they investigated the incident and presented a brief of evidence to the Work Health and Safety Prosecutor.In sentencing, Judge Jeffrey Clarke said Mr Dawson’s death was avoidable and that Mastermyne’s criminal negligence contributed significantly to it.Mining and Energy Union general vice president Stephen Smyth said the conviction was a milestone for justice and accountability.“This conviction sends a powerful message to the industry that negligence resulting in the death of a worker will not go unpunished,” he said.“Workers have campaigned for these laws, and this decision reaffirms that all workers are entitled to a safe and healthy workplace — and also entitled to justice when safety is undermined.”The MEU says its Industry Safety and Health Representatives recommended prosecution after investigations indicated Mastermyne’s strata control systems were inadequate.The union has also raised concerns that the penalty could be covered by Mastermyne’s insurance arrangements and has called for the relevant laws to be amended to prevent this.

Australia’s renewables deliver security during crisis
Australia’s electricity sector is showing significantly greater resilience to global energy shocks compared to the 2022 crisis, despite escalating geopolitical tensions in Iran driving sharp increases in global fuel prices, according to Wood Mackenzie.Despite oil prices surging more than 60% and Asian spot gas prices doubling compared to last year, Australian wholesale electricity prices have remained relatively subdued at about $70/MWh in Q1-Q2 2026, according to Wood Mackenzie.This is a stark contrast to the 2022 Russia-Ukraine crisis, when similar global fuel price shocks drove National Electricity Market (NEM) wholesale prices up by about 200% to average above $250/MWh.Wood Mackenzie energy storage and solar senior research analysis Natalie Thompson says this divergence reflects a structural shift in Australia’s power system.“Growth in renewables and batteries, reduced reliance on gas-fired generation, and the rise of distributed energy resources are materially lowering exposure to international fossil fuel markets,” she said.“Australia’s energy transition is now delivering tangible energy security benefits alongside emissions reductions.“While vulnerabilities remain to particularly from extreme weather events and supply-demand imbalances, the country's power sector is steadily decoupling from global fossil fuel market volatility.”Battery storage has emerged as a critical factor in this transformation, with batteries' share of price-setting rising from about 2% in early 2022 to about 20% by late 2025, while gas has decreased from 10% to less than 5%, according to Wood Mackenzie.Battery output tripled in Q4 2025 compared to Q4 2024, whilst gas generation declined almost 30% year-on-year during the same period, Wood Mackenzie reports.The report also found that Q2 of FY26 saw renewable energy reach record penetration levels across the NEM with midday solar oversupply now routinely driving wholesale prices to near-zero and, in some states, into negative territory, enabling battery systems to charge at minimal cost and discharge during evening peaks to replace traditional gas-fired generation.Wood Mackenzie's analysis highlights that Australia's distributed solar revolution has reached material scale, with more than 4.3 million rooftop solar systems installed nationally.The current fuel crisis may also be accelerating transport electrification across the country. March 2026 sales figures show battery electric vehicles capturing more than 14% of new car sales, with total electric vehicle share exceeding 20%, double the figures recorded in March 2025, according to Wood Mackenzie data.However, residual vulnerabilities remain with “dark doldrums", or extended periods with little sun or wind, still requiring dispatchable backup generation currently dominated by gas-fired plants.“Today’s batteries are highly effective for short-duration storage, but they cannot sustain the system through multi-day low renewable periods,” Ms Thompson said.“Longer-duration storage solutions, such as pumped hydro and extended-duration batteries, will be critical to ensuring reliability."The key question now is whether Australia can maintain the momentum of renewable and storage deployment to address remaining vulnerabilities before scheduled coal plant closures, to ensure the energy security dividend can be sustained."Addressing these challenges requires coordinated rollout of generation, storage and network infrastructure investments, according to Wood Mackenzie, including longer duration storage technologies such as 8-hour-plus batteries and pumped hydro to provide extended firming capacity during unfavourable weather patterns.

Westgold builds cash despite softer production
Westgold Resources (ASX: WGX) reported strong cash generation in Q3 FY26, bolstered by a rising gold price, while maintaining full-year production guidance.The company produced 93,145oz of gold during the quarter, bringing year-to-date output to 288,500oz, with production impacted by lower head grades and reduced contribution from ore purchase agreements compared to the previous quarter.Westgold maintains its FY26 production guidance of 345,000-385,000oz, with operations expected to strengthen in the June quarter following improved mining conditions.All-in sustaining costs were $2931/oz excluding ore purchase agreements while AISC including ore purchase agreements fell to $3338/oz from $3466/oz. Full-year costs are expected to land towards the upper end of guidance, reflecting inflationary pressures and operational decisions aimed at maximising cash flow.A key highlight of the quarter was Westgold’s cash performance, with the company delivering an underlying cash build of $285m and closing the period with $856m in cash, bullion and liquid investments, up $202m quarter-on-quarter.Operationally, performance across the portfolio was mixed. Lower production reflected reduced grades from the Starlight mine, lower ore purchase volumes in the Murchison and temporary ventilation constraints at Beta Hunt which have since been addressed.Mining productivity improved across several operations, with underground equipment performance lifting and stockpiles building across the Murchison hubs, positioning the company for stronger output in the June quarter.Westgold continued to advance growth initiatives during the period, including approving a final investment decision for the Higginsville expansion, which will increase processing capacity to 2.6mtpa.The company is also progressing Bluebird-South Junction and Beta Hunt as cornerstone assets for future growth.Westgold strengthened its balance sheet, establishing a $600m unsecured credit facility, while remaining debt free and unhedged retaining full exposure to the gold price.

South32 flags $1.5b Hermosa cost blowout
South32 (ASX: S32) has lifted Taylor growth capital at its Hermosa project in Arizona by $1.5b (US$1.1b), while pushing first production out to the second half of FY28.  Pre-production capital expenditure has been brought up to about US$3.3b, with the miner citing scope changes, higher construction costs and broader inflationary pressures including the impacts of US tariffs.  South32 now expects Taylor’s 4.3mtpa processing plant to achieve nameplate capacity by FY31. The delay has been attributed to contractor performance and productivity challenges in shaft construction, with mitigation measures only partially offsetting impacts on development timelines.  Despite the changes, South32 said updated studies continue to support Taylor as a large-scale, long-life underground operation, with an initial operating life extended to about 33 years, up from 28 years at final investment approval. The project is expected to deliver about 10.4mt of zinc equivalent production over its life, including 3.7mt of zinc, 4.6mt of lead, and 247moz of silver, with steady-state production averaging about 346,000tpa of zinc equivalent.  At steady state, the project is expected to generate average annual EBITDA of US$650m, with a post-tax net present value of about US$3.1b, based on long term pricing assumptions. Hermosa, which also includes the Peake copper deposit and Clark battery-grade manganese deposit, is positioned as a regional-scale development with potential to supply critical minerals across multiple decades.  
The quarry proposal was referred to the WA EPA almost 10 years ago.

WA EPA rejects sand and limestone quarry
The WA Environmental Protection Authority (EPA) has recommended against a proposal to extract sand and limestone from a quarry at Preston Beach.The proposal, from Carlo Doyle’s Haulage, would involve extraction, screening and crushing, as well as grading and maintenance of Preston Beach North Road for haul truck access.The majority of material proposed for extraction would be used for the supply of agricultural lime.WA EPA chair Darren Walsh says the proposed quarry area is bordered on three sides by the Yalgorup National Park, an internationally recognised Class A Conservation Reserve and the second largest National Park on the Swan Coastal Plain.“The natural features of the Park are of high social significance, and the area is a popular recreation and camping destination for nature-based tourism,” he said.“Monthly visitor numbers are upwards of 70,000 during peak holiday periods and a single, unsealed access road made amenity impacts a key consideration during this process.“During what has been an unusually lengthy environmental impact assessment, largely due to the proponent’s delays in providing adequate information, the EPA encouraged the company to take measures to mitigate impacts.“However, while they made an effort to address haulage impacts, adequate mitigation measures were not provided, and it was beyond the proponent’s authority to undertake the management of third party-operated haul truck activities on a public road.”Mr Walsh said such management was necessary to ensure that the public’s enjoyment of the values of the national park was protected.“So in this case the EPA believes that noise and dust from combined quarry operations and truck haulage will result in unacceptable environmental impacts,” he said.Two-way haul truck movements associated with the proposal, seasonally between December and April, were estimated at up to 44 per day for the 20-year life of the quarry, according to the WA EPA.The report is now open for a three-week public appeal period, closing May 21, 2026, with the Minister for the Environment making the final decision on the proposal.

Fortescue partnership lifts STEM in Pilbara schools
Students at Hedland Senior High School are gaining hands-on experience in drone technology and STEM pathways through a partnership with Fortescue (ASX: FMG). The three-year agreement, announced in 2025, includes a $600,000 investment from Fortescue to support a STEM education program, upgrade the school’s Technology Hub and expand vocational and tertiary pathways for students. The partnership is aimed at strengthening industry-linked education opportunities in WA’s Pilbara region. A key focus of the program has been the transformation of the school’s technology hub into an innovation centre supporting drone technology, engineering, coding and immersive learning, with students learning to operate and program drones while developing skills in aviation safety, mapping and data collection. Fortescue approvals, communities and services director Rosli Wheelock says the initiative is designed to connect students with emerging industries in the region. “Programs like this are about making sure students in the Pilbara can see themselves in the industries shaping the future of our region” he said.  “These technologies are already used across the Pilbara in mining, logistics and environmental management.” The program has also enabled three teachers to gain qualifications to deliver training toward a remote pilot licence and Certificate III in Aviation (remote pilot), providing students with access to industry-recognised credentials while still in school.  Students are applying their skills to practical scenarios such as bushfire assessment, disaster response, medical supply delivery and environmental monitoring, aligning classroom learning with real-world applications. The program has also contributed to increased enrolments in STEM and industry-aligned subjects, including engineering pathways, with strong participation from First Nations students. Participation in trade and engineering pathways has also grown, with students progressing into school-based traineeships and pre-apprenticeships in engineering and technology. The partnership will continue to expand, with plans to integrate immersive technologies into Two-Way Science, combining local cultural knowledge with digital tools and technology.  
Off the Record: The panic buying paradox

Off the Record: The panic buying paradox
Humans innately desire predictability. During times of crisis, it’s only natural to seek a sense of control in an unpredictable environment.While the concept of preparedness is part of our basic survival instincts, it took root as a broader movement during the Cold War as fears of nuclear annihilation ran rampant.During this time, the US Government encouraged citizens to build fallout shelters and schools even ran bomb drills — not that there’s much anyone can do to survive a mushroom cloud.Out of this anxiety, a survivalist movement grew.Survivalists, or doomsday preppers, are traditionally associated with extremism in the form of right-wing conservatism and radical anti-government conspiracy theories.The stereotypical survivalist is a white, backcountry, conservative male who may or may not also be bordering on deranged. However, as anxiety about the state of the world rises, the number of preppers globally are growing and as a result, the demographic is changing.During the height of the COVID-19 pandemic, prepping moved from a fringe culture to a mainstream response — and one that kind of seemed reasonable.With the cost of living rising and supply chains being frequently disrupted by geopolitics and extreme weather events, this movement is growing in popularity as everyday people seek self-reliance.Though the average person is unlikely to have months’ worth of supplies stockpiled in a bunker in case of complete societal collapse, they now tend to err on the side of caution.This is evident if you grab an extra carton of eggs when the shelves look a little sparse. Or if you decide to head down to the servo and fill up after reports that fuel prices are going to jump over night.These seem like perfectly reasonable decisions. The problem is when individual rationality morphs into collective irrationality.What starts out as a handful of somewhat sensible people taking minor proactive measures can quickly escalate into many people making the same decisions simultaneously. And when that feared scarcity is unfounded rather than genuine, panic buying can create the very shortages it is intended to insulate against as collective action overwhelms fragile systems.This is the panic buying paradox. And we are seeing it in real time with fuel supplies.People are rushing to buy fuel because they think it will run out, and it’s running out because they are rushing to buy it.At an industry event this morning, Prime Minister Anthony Albanese called panic buying “pretty bloody stupid”. Despite this sentiment, when I see others filling up portable fuel tanks at the bowser, I am overcome with a nagging sense that those people know something I don’t.Present concerns are understandable with Iran’s effective closure of the Strait of Hormuz driving crude oil prices well above US$100 a barrel.The Philippines have already declared a national emergency due to severe fuel shortages. And in Australia, fuel prices have increased by about 40% since the start of the war.Most Australians don’t panic buy or hoard supplies; they buy a little extra “just in case”. Are you buying an extra packet of toilet paper when the shelves look a little low? That seems reasonable when you remember the COVID-19 toilet paper crisis of the not-so-distant past. Are you a mobile business owner that just saw media coverage suggesting fuel could be 40% more expensive tomorrow? You might want to grab your keys and fill up. On second thought, grab your jerry can too.The problem isn’t that these decisions are irrational; it’s that these “just-in-case” purchases are combining with a “just-in-time” supply chain. This means stock is on trucks, not in back rooms. This keeps costs low, but it also assumes tomorrow will look exactly like today. Even a small shift along the supply chain can look like a complete system failure.During the pandemic, we saw what happens when supply chains fail to absorb external shock. Those wounds are barely healed. As a new crisis looms, it’s understandable that people want to take matters into their own hands.A perceived lack of transparency, fairness and compassion from decision-makers during unprecedented crisis eroded Australian’s confidence in their governments ability to protect them. Many Australians now are untrusting of the government to plan for times of crisis. Fairly so. The pandemic demolished public trust.Australia sits at the end of a very long and fragile fuel supply chain. Much of what we consume passes through the Strait of Hormuz off the coast of Iran. The cascading effects of the war are now dramatically interfering with our supply chains.Rather than labelling people queuing at petrol stations as irrational, we should acknowledge that we don’t know their personal circumstances. We don’t know if their livelihood depends on their access to a vehicle. We don’t know if the fuel will be used to run essential generators. Possibly most importantly, we don’t know if they have the capacity to absorb a 40% rise in fuel prices.Even if you think doomsday preppers are batty and panic buying is “un-Australian”, the lesson isn’t that people are irrational: it’s that our supply chains are ineffective.Neither survivalism nor panic buying is inherently evil. But neither is virtuous if it comes at the expense of others. The goal shouldn’t be to outlast everyone else in a crisis — it should be to build a society where there is no need to stockpile in the first place.Although politicians are urging the public not to panic, they risk encouraging the opposite effect and further fostering fear. It seems the next plight the government faces is a crisis of trust.Off the Record is The Australian Mining Review’s weekly column.
