Boss Energy shares plunge on issues at uranium mine
Boss Energy shares on Monday afternoon were down 42.2 per cent to a three-year low of $1.965 after the Perth-headquartered company made the announcement about its Honeymoon mine, 80km northwest of Broken Hill.
Boss said that based on more than 12 months of resumed operations, it had identified "potential challenges" that could prevent Honeymoon from ever achieving its forecast production target of 2.45 million pounds of yellowcake a year.
"We're confident that we'll get at least 1,600,000 pounds," chief executive and managing director Duncan Craib told analysts in a conference call on Monday.
The issue is production drilling at 15 to 20 metres of spacing has found less uranium mineralisation than Boss had inferred from its 2021 feasibility study, which relied on drilling at 60 or 70-metre spacing.
An independent review by experts will commence shortly to determine the extent to which this will affect assumptions from the early feasibility study, Boss said.
The Honeymoon mine opened in 2011 but operations were suspended just two years later, after a plunge in the price of uranium.
Boss bought the mine in 2015 and it resumed operations in 2024.
"It really has been a tremendous achievement that since the start of commissioning in April (2024), we've produced over one million pounds of uranium to date," Mr Craib said.
The chief executive, who is stepping down at the end of September, told analysts in response to a question that it was too soon to say how the mineralisation findings might affect Honeymoon's estimated mine life of 10-plus years.
"The mine itself is off to a flying start," he said.
It is profitable and Boss Energy has no debt, he added.

Woodside to operate Bass Strait venture boosting east coast gas supply
Woodside Energy has taken a decisive step to ease the strain in the east coast gas market, striking a deal with ExxonMobil to take over as operator of its Bass Strait venture and opening the way to developing gas fields without its partner. The change in the management of the Gippsland Basin gas venture, the first since production started in 1969, will mean about 1200 Exxon workers and contractors will transfer to Woodside, representing a major expansion of the Perth-based producer's presence on the east coast, where it currently employs 15 people.

US giant ExxonMobil gives up control of critical Australian gas supplies
Oil and gas major ExxonMobil will hand over management of eastern Australia's biggest source of domestic gas for the first time since the 1960s, as its joint venture partner sets its sights on new wells to eke out more supplies of the fossil fuel from ageing offshore fields. More than 600 workers at ExxonMobil subsidiary Esso Australia were told on Tuesday morning that their jobs and the operatorship of Victoria's Gippsland Basin joint venture – a network of offshore platforms in Bass Strait and processing plants at Longford and Long Island Point – would be transferred to Perth-based Woodside Energy from next year. Under the deal, ExxonMobil and Woodside would remain 50:50 equity partners, with their responsibilities for decommissioning the ageing infrastructure unchanged, the companies said. However, Woodside, as operator, would gain the ability to independently invest in future oil and gas wells or expansion projects in Bass Strait. On Tuesday, Woodside said it had identified four potential development wells that could deliver up to 200 petajoules of new gas into the tight east-coast domestic gas market – enough to supply about 40 per cent of a year's total demand. The news comes as authorities, including the Australian Energy Market Operator (AEMO), sound warnings that millions of households in Victoria, NSW and South Australia are at risk of gas shortfalls during periods of elevated winter heating demand in as little as three years unless new supplies are made available. The vast Gippsland Basin gas fields, which have kept gas-reliant homes and businesses on the eastern seaboard well supplied for decades, have entered a period of rapid depletion, with scant new projects available to replace them. Loading Producing and burning natural gas releases planet-heating carbon dioxide and methane emissions, which governments are trying to dramatically reduce in a push to combat dangerous global warming. Although more Australians are making the switch from gas-powered appliances to electric alternatives, demand is not falling at the speed needed to avert supply shortfalls in the coming years. Australia's east coast gas market is on a path toward a 'structural shortfall,' global consultancy Wood Mackenzie warns. 'Gas demand on the east coast remains resilient, but new supply is not keeping pace,' it said.
