Resources segment operational update TRUSTCO GROUP HOLDINGS LIMITED Incorporated in the Republic of Namibia and registered as an external company in South Africa (Registration number 2003/058) (External registration number 2009/002634/10) NSX share code: TUC JSE share code: TTO ISIN Number: NA000A0RF067 (“Trustco” or “the Company”) RESOURCES SEGMENT OPERATIONAL UPDATE: MEYA MINING SALE OF DIAMONDS MAY 2018 Trustco is pleased to advise Trustco shareholders (“Shareholders”) of the following operational update related to Meya Mining’s exploration program and wishes to inform Shareholders of following operational activities: - Whilst development at the Bardu and Waterloo bulk samples are ongoing, Meya extracted more kimberlite from the Meya River bulk sample approximately 375 metres above mean sea level (“mamsl”) along a 100m strike of Dyke Zone B. This sample produced 2 325.17 carats during the first pass of the Run of Mine (“RoM”) material through the plant, including a 11.09 carat Type IIa diamond which was sold for USD 13 014.70 per carat. - A second pass of the DMS tailings audits from the Meya River domain, crushed down from 12 mm to 8 mm yield an additional 969.95 carats whilst similar audits from the Bardu sample yielded 232.34 carats. - All three diamonds parcels (RoM and DMS audit tailings) were sold on tender in Antwerp during the third week of May 2018. Notwithstanding the overall smaller size distribution, from the DMS audit tailings, the average price per carat achieved, exceeded expectations. Sample Carats Average Value USD/Carat Meya River - RoM 2 325.00 358.68 Meya River – audit tailings 929.01 135.35 Bardu – audit tailings 205.00 123.11 Total 3 459.01 285 - In addition to Dyke Zone B, Meya started exploration on the Simbakoro Dyke, which is located some 800m north of Dyke Zone B running on a parallel orientation. Excavations on the Dyke indicate a potential strike length of ?2.7km. Initial observations indicate strong geological correlation to Dyke Zone B in that it also contains abundant olivine macrocrysts and garnets. Samples were collected for export to Canada for further analysis. Resource development work is scheduled to delineate the dyke as well as to collect a bulk sample which will enable inclusion in the Resource Statement scheduled for the latter part of 2018. Meya Mining’s Competent Person, SRK Canada, is in the process to compile an interim report regarding the exploration progress which will include exploration results indicating the potential of the areas (dyke domains) under investigation. This report will be included in the 2018 Integrated Annual Report.
