Decklar and Millenium have entered into a new sale and purchase agreement with DMCL to deliver an initial 5,000 bbls to the Duport refinery in Edo State, Nigeria, followed by a minimum 2,500 bbls per month thereafter. This agreement expands the customer base for the sale of crude oil from the Oza Oil Field and gives Decklar and Millenium an alternate delivery location for additional volume.

Continued Trucking and Sale of Crude Oil to Edo Refinery

Trucking of oil from the Oza Field has continued to the ERPC facility in Edo State, Nigeria, and delivery of an additional batch of 5,000 bbls has been completed. Total deliveries of approximately 17,000 bbls have been completed to date, with invoices issued for 15,000 bbls. Payment for the first 5,000 bbls invoice has been received, and payment for the subsequent invoices is expected in the next week under the terms of 30,000 bbls sales agreement. Additional deliveries are anticipated to continue on an ongoing basis. The current total available fleet of 20 contracted trucks is expected to consistently deliver approximately 5,000 bbls per week.

With the execution of the additional 150,000 bbls sale and purchase agreement with ERPC and the execution of the new DMCL agreement, Decklar and Millenium plan to secure additional trucks and permits to service the increased sales volumes and allow for the Oza Oil Field to be produced at full capacity from the Oza-1 and Oza-4 wells."
