Greenheart Gold Inc. Provides An Update On Its Exploration Projects In Suriname And Guyana

Greenheart Gold is an exploration company looking to build on a proven legacy of discoveries and mine development in the Guiana Shield. The Company was created as a "spin-off" from the business combination between G Mining Ventures Corp. and Reunion Gold Corp.. Following the business combination on July 15, 2024, Greenheart Gold acquired Reunion Gold's interests in the Majorodam and Abuya gold projects described below and was funded with C$15 million in cash.

The Company is led by former executive team members of Reunion Gold, a team that has a proven track record of both exploration success and mine development, and most recently noted for the discovery and delineation of the Oko West deposit, the largest recent gold discovery in the Guiana Shield. Greenheart Gold's strategy is to focus on gold exploration in the Guiana Shield, an area that still remains under-explored, even though it hosts highly prospective geologic terrains and already boasts numerous gold deposits. The Company is aiming to build a robust portfolio of early-stage exploration projects that encompass the key factors in the geological setting that the exploration team feels were important in the Oko West discovery. Greenheart is focused on gold projects located in Guyana and Suriname, both providing an attractive combination of favorable geology and supportive governments. The Company is currently engaged in numerous discussions to build its exploration project pipeline.

Majorodam, Suriname

Greenheart Gold has an option to acquire a 100% interest in the Majorodam project, located within the Marowijne Greenstone Belt and approximately 120 km south of Paramaribo in Suriname. The optioned area is adjacent to paved roads, about two and a half hour's drive south of Paramaribo. Greenheart Gold believes that the Majorodam project is highly prospective and exhibits favorable geology, including reactive host rocks, regional and property scale deformation events including polyphase folding, and the presence of abundant artisanal workings within drainages downstream of the main target areas. Majorodam is situated on the southern limb of the same regional fold structure that hosts the 1.1 Moz Au @ 1.9 g/t Au Saramacca deposit (IAMGOLD 2022 Annual Report), which is located on the northern limb, approximately 12 km from Majorodam as shown in Figure 2. The limbs of this structure contain an abundance of both active and historic alluvial gold mining. Despite the favorable geological setting and excellent access, Majorodam has been largely unexplored for primary gold deposits using modern exploration methods.

A detailed aeromagnetic survey was flown by the concession holder in 2019 and from this data the Greenheart Gold exploration team has interpreted multiple folding events on the property. Greenheart Gold believes that polyphase deformation events could be a key feature of many deposits found in the Guiana shield, and also relates to the Oko West discovery in Guyana. The Majorodam Project is described in more detail in the Majorodam Technical Report prepared by Ross Sherlock, Ph.D., P.Geo. of Tantalus Geoscience Services Ltd. available on the Company's website. Initial work has commenced at Majorodam with detailed geological mapping surveys underway and the first phase of a reconnaissance soil sampling program also in progress.

Abuya, Guyana

Abuya is an early-stage exploration project located in the northwest portion of Guyana, adjacent to the Cuyuni River and on the western margin of the Aurora batholith and Devil's Hole Gneiss complex, approx. 15 km west of Zijin's producing Aurora Gold Mine (see Figure 3). Greenheart Gold has an option to acquire a 100% interest in the Abuya Project consisting of twenty medium scale mining permits totaling 90 square kilometers in area. A local prospector is currently carrying out small scale alluvial mining activities with significant success. Greenheart is working in partnership with the prospector to carry out its exploration programs which contributes to its ability to carry out efficient and effective use of exploration funds by sharing camp and equipment operating costs. The project meets most of the geologic criteria that the Greenheart Gold team feel are important indicators for the potential occurrence of Paleoproterozoic gold mineralization in the Guiana Shield.

Despite the promising geologic setting, the project area has undergone no previous exploration for primary gold deposits, with the area only being noted in a 1968 report that referenced some initial alluvial gold mining activities in the area. The geologic setting at Abuya, which has been confirmed by phase 1 reconnaissance mapping, appears to be similar to that of both Aurora and Oko West with the optioned area being characterized by volcano-sedimentary rock units that are folded and locally sheared in proximity to the margin of the gneiss-granite complex to the east. Additionally, the Ammamuri granite is noted to intrude along the orientation of a regional fold axis and dominates the northwestern portion of the permits. The combination of the identified folding and deformation events with the reactive host rocks and the rheological contrasts between the adjacent rock units creates a prospective setting for gold mineralization. Greenheart has already completed a phase 1 reconnaissance mapping and soil sampling program at Abuya after only three weeks of field activity on the project, with results pending.

About Greenheart Gold Corporation

Greenheart Gold is an exploration company that builds on a proven legacy of discoveries in the Guiana Shield, a highly prospective geologic terrain that hosts numerous gold deposits, though remains relatively under-explored. The Company is aiming to build a portfolio of early-stage projects in Guyana and Suriname that are prospective for orogenic gold deposits. Greenheart Gold is a Canadian corporation that was created as a "spin-off" from the business combination between G Mining Ventures Corp. and Reunion Gold Corporation completed on July 15, 2024. The Company is led by former executive team members of Reunion Gold, a team that was most recently noted for the discovery and delineation of the Oko West deposit in Guyana, which is set to become the next gold development project in the region.
