16 Source: Company Reports; midpoint production guidance for 2020 Kouroussa Exploration Upside

Results from a more in depth data review of the Kouroussa project conducted as part of Hummingbird’s initial due diligence highlighted:

• The high grade nature of the Kouroussa gold system which includes Koekoe, Kinkine, X-Vein and Bag Farm – Junction

• Further upside potential for open pit and underground resources outside of the current stated mineral resource of 1.1Mozs

• The presence of gram metre intervals greater than 100 gram metres

o A sign of the potential world class nature of the Kouroussa gold system

o Further focused exploration is planned to confirm this

• All deposits remain open and further exploration work is required to enable Hummingbird to fully evaluate the potential of the Project

18 Hummingbird’s plans for Kouroussa LEVERAGE THE COMPANY’S EXPERIENCE IN YANFOLIA TO DEVELOP A SIMILAR PROJECT

• Advanced development stage as well as scale, mining and processing similarities with Yanfolila will allow to fast track production

• Once further technical studies are completed, targeted during 2020, Hummingbird will then move the Project to production

• Hummingbird’s West African banking partner, Coris Bank International, has confirmed they are fully supportive of the transaction and willing to fund the construction

1. A preliminary economic assessment is preliminary in nature and include inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Additionally, inferred mineral resources are subject to uncertainty as to their existence and their economic legal feasibility. See “Disclosure” on page 1 and “PEA Assumptions” in the Appendix. 2.

28 Regional geology

• A major crustal scale shear zone traverses the Dugbe project licence area in a NE-SW orientation, referred to as the Dugbe Shear Zone (DSZ)

• Dugbe Shear Zone is a highly attractive mining region

• Hummingbird explored 12,000 km2 before defining the Dugbe Project area

• The area of Birimian-age rocks is recognised as the second largest gold producing area in the world

• Licence area seen as one of the last remaining unexplored regions of the Birimian

29 Exploration history

• The Dugbe Project MDA comprises four exploration permits: Dugbe, Joe Village, Nemo Creek and Tiehnpo

• Grassroots exploration conducted between 2006 and 2014 included:

• Stream sampling

• Soil sampling

• Airborne and ground geophysical surveys

• Topographic surveying (LiDAR)

• Trenching

• Diamond and RC drilling

• RAB drilling
