Operations Update

Nostra Terra aims to become cash flow positive on a Group-wide basis over the course of 2017. Net cash flow generation at Pine Mills is making an increasingly significant contribution to enabling the Company to reach this goal.

During the first 6 months of ownership of the Pine Mills oil field, Nostra Terra focused on decreasing Lease Operating Expenses ("LOE") and overheads, upgrading infrastructure to help stabilise production, followed by workovers to increase production. Nostra Terra is pleased to report that these efforts have delivered an immediate improvement in field performance at Pine Mills.

During the difficult winter months, the Company used this time to upgrade infrastructure and wells to help stabilize production. As a result of these activities average production for the six-month period was 91bopd and the field has been in profit for six consecutive months since Nostra Terra acquired Operatorship.

Recent workovers have further increased production, with the month of May delivering the highest monthly production yet. Current average daily production at Pine Mills for May is 118bopd. Nostra Terra will continue to perform workovers on identified opportunities to increase production further.

The table below summarises the six month operational performance, on a 100% WI basis, at Pine Mills between 01 November 2016 and 30 April 2017.

In total, Nostra Terra sold a gross 16,600 barrels of oil at Pine Mills between 01 November 2016 and 30 April 2017. This generated net revenue (after royalties and severance tax) of $586,355. Total LOE, otherwise know as "Lifting Costs", were $264,799. The average LOE per barrel of oil produced was $16.31. The net operating profit for the period at Pine Mills was $321,556.

Nostra Terra currently owns an 87.5% WI in Pine Mills. However, as a result of the outstanding monies owed by Hammerhead Management Partners ("Hammerhead") (please refer to the Company's 24 May 2017 announcement for further information), the Board anticipates this will increase to 100% in the near future. As such, this has permitted Nostra Terra to retain 100% of all surplus cash flow generated at Pine Mills. This will be set off against monies owed by Hammerhead.

Nostra Terra is encouraged by the results of operational improvements it has made at Pine Mills and still targets average stabilised average production rates of between 130 and 150bopd. New workovers are planned to increase stabilised production rates over the coming months, using internally generated funds. Nostra Terra will also work to further reduce operating expenses (lifting costs) and thereby improve operating margins.

Reserves Report

The Independent Reserves Report, released on 05 April 2017, confirmed Nostra Terra's net proven reserves at Pine Mills were 481,350 net barrels of oil. These net proven reserves were assigned an NPV10 valuation of US$3.53million. These results were calculated on the basis of Nostra Terra owning an 87.5% WI in Pine Mills.

Matt Lofgran, Chief Executive Officer of Nostra Terra, commented:

"With 6 consecutive months of operating profit and now increasing production rates, Pine Mills continues to generate solid cashflow for Nostra Terra.

"Our primary focus as a Company is to increase production on assets that can generate free cash flow at current lower oil prices. Pine Mills is a great example of this, where the net cash flow covers the majority of our corporate overheads.

"We look forward to updating on further progress on Pine Mills as well as other areas of our portfolio."
