Mosman Oil & Gas (AIM:MSMN) Planned Cinnabar Development Drilling and Placing

Mosman Oil and Gas Limited (AIM: MSMN) the oil exploration, development, and production company, announces a £1.1 million conditional placing to fund the drilling of the first re-development well in the Challenger Project in Texas, of which Mosman has a 97% working interest.

If the targeted production rates are achieved, Mosman Net Production could increase 88% from 130 boepd (as reported for quarter ending March 31, 2022) to circa 245 boepd.


In order to fund the planned drilling and anticipated completion costs at Cinnabar, the Company has raised £1.1m (before expenses) by way of a placing of 1,375,000,000 new ordinary shares of no par value in the capital of the Company (“Placing Shares”) through the company’s broker Monecor (London) Ltd, trading as ETX Capital, at a placing price of 0.08p per share (the “Placing Price”) (the “Placing”). Investors are also receiving a one for two warrant exercisable at a price of 0.16p with a term of 24 months, 687,500,000 warrants are being issued in aggregate (the “Placing Warrants”).

Based on current production rates and current oil and gas prices the Company is currently operating above cashflow breakeven (not including major capital costs such as EP145 seismic, larger workovers that are not yet planned, and other potential drilling at Cinnabar if the first well is a commercial success).

That situation will be further improved with a successful well at Cinnabar.

This means that the Placing will allow for the drilling and development at Cinnabar and, based on a successful well, is expected to provide sufficient working capital for the next 12 months.

The Challenger Project and Cinnabar Lease

The Challenger Project is focused on the Cinnabar Lease, a 348-acre lease Held By Production. This area was originally drilled in 1989 by Ballard Exploration on Atlantic Richfield Company leases and has produced oil and gas from Wilcox sands since then. Mosman acquired 97% of the lease in 2020 and agreed to farmout 12% with Contour Exploration and Production LLC (“Contour”), in which Contour may earn a 12% working interest in the Cinnabar Lease when a well is drilled, in return for contract operator services. A recent technical review included reprocessing and interpreting 3D seismic. Updated geological mapping can now be used to optimize the location of development wells.

Cinnabar has the potential to be a transformational project for the Company. Mosman sees the potential for multiple development wells in the 348-acre Cinnabar lease as the standard Wilcox spacing is 40 acres per well. The economics to drill are compelling with the current oil and gas price.

Drilling the first well is planned for August-September 2022 and will be the next well drilled by Mosman. The location has been chosen based on geological mapping and selecting a location near existing roads and gas pipelines.

Cinnabar Reserves

A Reserve Report completed in 2017 indicated the project has Reserves (100% working interest, net of royalties) as follows (thousands of barrels of oil equivalent “MBOE”):

This Reserves Report was prepared by an independent petroleum engineering firm in June 2017 and conforms to SPE-PRMS petroleum guidelines. Reserves are net of royalties, which are a standard 25%. The Report has not as yet been updated for the recent technical work.

Discussions with an independent engineer have indicated that based on prior production, the development well is estimated to produce at approximately 100 bopd and 200 Mcfd. Mosman considers that to be a reasonable target, however the technical work completed will mean the well is being targeted at a crestal location and may perform better than the old wells.

John W Barr, Chairman, said: “Recent focus in respect to the USA projects has very much been about maximising production. That is reflected in the recent strong production rates in the March quarter.

“We are pleased that our early investment in Cinnabar has matured at a time of strong oil and gas prices, making this well a compelling investment and providing significant further growth potential.”

Admission to AIM and Total Voting Rights

The Placing is conditional on, inter alia, the Placing Shares being admitted to trading on AIM. Application has been made to the London Stock Exchange for the Placing Shares, which will rank pari passu with the Company’s existing issued ordinary shares, to be admitted to trading on AIM and dealings are expected to commence at 8:00 a.m. on or about 17 May 2022.

Following the issue of the Placing Shares, the Company’s share and total voting rights will comprise 5,220,138,052 Ordinary Shares of no par value and the Company does not hold any shares in treasury .

Consequently, the above figure may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the Financial Conduct Authority’s Disclosure and Transparency Rules.
