History

Winchester listed in 2014 to chase Texas Permian oil, found real production at Mustang, then diluted heavily, lost its board in a 2025 shareholder revolt and now stretches thin cash.

2014-2016: Listing and the White Hat wells

Winchester listed on the ASX on 18 September 2014 after an A$20 million raising at A$0.20 a share, aiming at oil in Texas's Permian Basin. It bought half of the White Hat 20#1 well from operator Carl E Gungoll Exploration (CEGX), then a 75% interest in 7,378 acres around it. In August 2015 it bought 8,062 more acres, taking net acreage to 17,432.

The first tests of the Thomas 119-1H well produced too much water. White Hat 20-1, however, began producing in May 2015. Its offset, White Hat 21#1, averaged 201 barrels of oil a day over its first 30 days and was booked with 162,000 barrels of gross 2P reserves (the best-estimate category). More offsets followed. White Hat 21#4 started in July 2016 and gross output from five wells passed 460 barrels a day. Not everything worked: the Patterson 1R well, a 25% interest, was plugged and abandoned.

2017-2018: Disappointing wells and a reset

In September 2016 Winchester agreed to join CEGX in seven more wells, and the setbacks began. Fracture stimulation on 38#1 broke into water and it produced no oil. On 1 March 2017 the CEGX arrangement ended and Winchester took over as operator of new wells outside the drilled 40-acre units, holding 75%.

To fund drilling it ran a 1-for-4 rights issue at A$0.09 in mid-2017, which took up only 53% of the offer (A$2.57 million), and in November placed about 35 million shares at A$0.10 to raise about A$3.5 million. John Kopcheff became chairman in September. The company then tried ultra-short radius laterals, short sideways drill legs meant to expose more rock. White Hat 38#3ML ended at under 10 barrels a day, and the 39#1L lateral lost its oil. In September 2018 ASX had the original investor presentation removed, and the company retracted its larger resource targets. It shifted to vertical drilling and cost cuts. Independent consultants estimated 7.796 million barrels of gross prospective resource (undiscovered) in October.

2018-2020: Mustang and Lightning

A December 2018 rights issue at A$0.02 aimed at A$2.85 million but raised only A$847,982 in the first round, with the shortfall to be placed with CPS Capital. The drilling it funded worked. White Hat 20#3 at the Mustang prospect flowed 306 barrels of oil a day in May 2019, and a development plan of up to 34 wells followed. Arledge 16#2, at the new Lightning prospect, flowed at 250 barrels a day in September. A placement at A$0.025 in August 2019 and a A$6.4 million placement at A$0.05 in November supported this. Net production hit a record 381 barrels of oil a day in October 2019. Shares on issue reached 687.6 million by end-2019.

In 2020 the company paused heavy drilling because of COVID-19 and the oil price fall, holding over A$6.5 million cash and no debt at end-February. A May audit put net reserves and resources at 11.2 million barrels of oil equivalent. The White Hat 2004 re-completion and the White Hat 3801 'Bonus Sands' test found no commercial oil.

2021-2023: New money, new wells, Varn

Founding managing director Neville Henry retired in January 2021, and chairman Laurence Roe resigned in April after three months as executive chairman. A year-end 2020 audit cut 3P reserves to 496 thousand barrels from 1,653 thousand. In May 2021 a placement of 312.5 million shares at A$0.016 raised A$5 million, lifting shares to 863.8 million. White Hat 2106 came in at 217 barrels a day on pump, and a White Hat 3902 recompletion helped lift net production to a record 611 barrels of oil equivalent a day by November.

In December 2021 Winchester bought the Varn Oil Field for US$415,000 plus drilling costs, with 1.068 million barrels of 2P reserves. It also farmed into the Group Prospect in 2022. Varn drilling began in 2022, with a surprise 80 barrels a day of primary oil from JVU#6 in February 2023, before any waterflooding (water injection to push oil out).

2024-2025: Board fights

The record is quiet for 2023 beyond Varn. In June 2024 the board was overhauled, with Rory McGoldrick joining. Director fees were cut, and a placement of 250 million shares at A$0.003 raised $750,000. An entitlement offer drew only $343,791. Westex Resources sued over the Group Prospect farm-in in August 2024 and abandoned the claim in May 2025. An offshore Peru term sheet with Jaguar Exploration was signed in March 2025 and terminated in June.

Shareholders then requisitioned meetings to remove directors. On 23 July 2025 the whole board was voted out, and ASX suspended the shares. Jason Peterson and David Wheeler were appointed on 31 July, restoring the three-director minimum. Chris Zielinski joined, and McGoldrick became part-time CEO. In September 2025 Winchester sold 30% of the Varn waterflood to a US investor group for US$112,000 upfront and 40% of further costs. JVU-5 began producing in November.

2025-2026: Stretched resources

In December 2025 a placement of 300 million shares at A$0.001 sought A$300,000. In March 2026 Winchester signed a binding term sheet for an offshore Indonesia study, with an option on 24.5% of any production sharing contract, and agreed to lend A$500,000 as bond collateral. It also took A$250,000 loan facilities each from Peterson's Celtic Capital and from McGoldrick to help with study costs. JVU-4 was completed in April, and water injection began in the June 2026 quarter.

At 30 June 2026 Winchester had A$206,725 in cash and 1,713,018,946 shares. June quarter revenue was A$581,780 at 65 barrels of oil equivalent a day. A$250,000 from McGoldrick's company was undrawn, and the Indonesia study was still running. Moore Australia replaced Hall Chadwick as auditor on 13 August 2026.
