Update on Oza field, Nigeria

San Leon, the independent oil and gas production, development and exploration company focused on Nigeria, notes the announcement made on 15 March 2023 by Decklar Resources Inc. ("Decklar") in Canada.  San Leon has a 11% shareholding in Decklar Petroleum Limited ("DPL"), the local subsidiary of Decklar operating in Nigeria, and has also made a US$5.5 million loan to DPL, via 10% per annum unsecured subordinated loan notes. 

As confirmed in its recent announcement on 1 March 2023, San Leon continues to explore a potential sale of its non-core investments in DPL although the completion remains subject to the purchaser finalising its own funding arrangements.

Part of the text of Decklar's announcement is set out below:

·   "Decklar Resources Inc. ("Decklar") and its co-venturer Millenium Oil & Gas Company Limited ("Millenium") have executed an addendum to the recently signed sale and purchase agreement to increase the total volume to be delivered by an additional 50,000 barrels of crude oil ("bbls") to the Edo Refinery and Petrochemicals Company Limited ("ERPC") in Edo State, Nigeria. This brings the total additional volume contracted to 200,000 bbls.

·    Trucking of crude oil has continued from the Oza Oil Field to the ERPC refinery, and total deliveries to ERPC have passed the 20,000 bbl mark under the 30,000 bbls crude sale agreement.

·    Decklar and Millenium have also made progress obtaining necessary permits to sell and export approximately 8,000 bbls previously delivered to Umugini Pipeline Infrastructure Limited ("UPIL") and held in storage at the Forcados export terminal tank farm.
