The audit appointment comes into force with immediate effect, with Liverpool-based SDG replacing incumbent auditor PKF Littlejohn after only two years handling the audit business.

PKF Littlejohn LLP has confirmed that there are no circumstances connected with its resignation which it considers should be brought to the attention of members or creditors of GoldStone.

In a statement to the London Stock Exchange, the board of GoldStone said it would ‘like to thank PKF for its service over the years’.

GoldStone is an AIM quoted exploration company with projects in Ghana, Senegal and Gabon that range from grassroots to advanced exploration.

The fee for the last audit reported in the GoldStone annual report for year end December 2017 was £25,418, down from the previous year’s total audit fee of £37,178.
