Competent Persons Report on the Ororo Field

Convertible Loan of £500,000

Sirius Petroleum (AIM: SRSP), the investing company focused on oil and gas exploration and development opportunities in Nigeria, is pleased to announce the results of a Competent Persons Report ("CPR" or "Report") for the Ororo Field ("Ororo") in OML 95 located in shallow waters offshore Ondo State.

Competent Persons Report on the Ororo Field

Sirius announces that independent petroleum consultants, Rockflow Resources Limited ("Rockflow"), have produced a Competent Person's Report ("CPR") for the Ororo Field. This valuation, subsequent to the technical volumetric description announced on 22nd April 2016, was commissioned to assist the Company with potential funding and vendor finance proposals.

Following comprehensive subsurface analysis, which confirmed a gross Mid to High Case liquid hydrocarbon volume range for the Ororo Field of 7.65 MMstb - 20.48 MMstb, Rockflow determined project economics using the Company's Field Development Plan ("FDP"), which reflects the optimal development strategy for the Ororo Field.

The results of the CPR, details of which are set out below, demonstrate a material valuation to Sirius as at 6th September 2016.

Summary of Rockflow's results:

· A Mid Case Net Present Value (NPV10) of the asset of $49.2m, based on a $50 per barrel flat real oil price for life of field

· The Mid Case scenario implies peak oil production at 6,000 stb/d and peak gas production at 25 MMScfd, which equates to combined peak production at 10,310 barrels of oil equivalent per day (boepd)

· The Ororo Mid Case has a positive NPV10 above $27/stb

· Sirius' entitlement to oil and gas production is greater than 40% of field production due to its entitlement under the FTSA to recover a higher share of its capital investment from production before distributing cash to other Partners

Highlights

Rockflow evaluated Ororo at a base reference oil price of US$50 per barrel and a gas price of US$3.50/Mscf (real terms flat)

Gas BOE conversion factor: 1 barrel of oil equivalent = 5800 cu ft gas

*Under SPE Guidelines, the hydrocarbons are classified as Contingent Resources and will convert into Reserves upon finalisation of approvals and agreements with contractors. The valuation methodology used by Rockflow provides for the commercial producible resources to be defined rather than the technically producible oil. Under the present oil price scenario this results in a modest change for the tail end volumes in relation to the volumetrics reported on 22nd April 2016.
