ment of the economics and production potential at Block 14 and drill testing of additional high-grade targets previously identified. Block 14 has exceeded our expectations and continues to demon- strate that it has a lot more to offer. The delivery of our Feasibility Study will estab- lish the initial economics of this project and will form the base for further growth of this exciting gold camp.” The Block 14 gold project is located close to Sudan’s border with Egypt, 900 km north of the capital Khartoum. The conces- sion covers 2 170 km 2 . Access to the project is by sealed road along the eastern bank of the River Nile to the town of Abu Hamad and then via a well-used desert road to the project area.  intersections of vein-hosted mineralisation and all ten holes into the core of the A4 Dome have intersected visible NPF contact mineralisation. The grades are also strong, with assay results from all three NPF inter- sections received to date including intervals greater than 2 % copper at the base. “The proximity of A4 Dome to the planned T3 processing plant makes it an attractive proposition which supports our strategy to increase production above the current target of 30 000 kt/a copper and build a long-term operation centred around T3.” 

Canada’s Orca Gold Inc, listed on the TSX‑V, has announced an updated Mineral Resource Estimate (MRE) for its Block 14 gold project in the Republic of the Sudan. This estimate – based on 111 761 m of drilling in 756 holes – will form the basis for the Feasibility Study due for delivery in November this year. The MRE of the Galat Sufar South (GSS) and Wadi Doum deposits comprises an indicated resource of 79,9 Mt grading 1,30 g/t Au for 3,34 Moz of gold and an inferred resource of 18,5 Mt grading 1,2 g/t Au for 0,71 Moz of gold (at a cut-off grade of 0,6 g/t). Intercepts demonstrate a higher-grade core within both the GSS and Wadi Doum deposits. It is anticipated that this will

result in the mining of higher grades in the early years of the project, significantly impacting economics. “The drilling completed in 2018 has been specifically aimed at developing min- eral reserves as part of the Feasibility Study. Given the increase in the scope of the Block 14 project, driven by the 2017 discovery of a major fresh water aquifer system and the successful resource drilling campaigns, we expect to see a significant positive change in the scale and scope of the project with the delivery of the Feasibility Study in November,” comments Richard Clark, CEO and Director of Orca Gold. “Exploration will now focus on the expansion of high-grade zones identified at Wadi Doum towards further enhance- at the A4 Dome, being localised vein- hosted mineralisation in the upper part of the dome and Ngwako Pan Formation (NPF) contact mineralisation which may form a flat lying ‘blanket’ underlying the dome, 450-500 m below surface. “We’re still in the early stages of under- standing the A4 Dome; however, we are encouraged by the potential for significant mineralisation within this large target,” comments MOD’s Managing Director, Julian Hanna. “Two holes have intersected wide

MOD reports encouraging drill results from A4 Dome ASX-listed MOD Resources reports further very encouraging results from drilling at the 70 %-owned A4 Dome, 8 km west of its T3 project in the Kalahari Copperbelt in Botswana.

A4 Dome represents part of MOD’s T3 expansion strategy to define additional sources of ore within the T3 Dome Complex that could enable future increases in produc- tion through the proposed T3 process plant. As previously announced by MOD, there are two distinctive types of mineralisation
