  • Debt free with $17.8 million cash on hand as at 31 December 2020 (unaudited)

Mnazi Bay Operations and Operational Outlook

  • Repairs to the MB-2 flowline were completed on time on 9 December 2020 and the well has continued to perform in line with expectations
  • A planned slickline campaign commenced on 22 January 2021 which primarily includes a continuation of the Mnazi Bay Partners’ ongoing pressure monitoring programmes

Reserves Update

RPS Group, an independent third-party reserves evaluator, performed a Competent Persons Report (“CPR”) for the Company with an effective date of 31 December 2020.  The updated full field 2P gross reserves for Mnazi Bay are 445.3 Bcf (90.8 Bcf being Wentworth’s share of net reserves).  This compares to 468.9 Bcf as at 31 December 2019. As full-year 2020 gross production totaled 23.9 Bcf (gross), this demonstrates a minimal change attributable to technical and economic factors to previous reserves estimates.

The NPV10 after tax for the 2P reserves as at 31 December 2020 is $116.6 million net to Wentworth. This compares to $118.6 million for 2019.  It should be noted that during 2020, Wentworth increased its cash position to $17.8 million (unaudited), while distributing $3.2 million in dividends, compared to cash of $13.5 million as at 31 December 2019.

“The results of our 2020 Competent Persons Report show the continued strong technical fundamentals underlying the Mnazi Bay field and its potential to generate strong, long-term free cash flows that form the basis of our sustainable dividend policy. We look forward to continuing to use our fiscal discipline and financial performance to create further value for shareholders.” Katherine Roe, CEO, said.
