Longueuil, Québec–(Newsfile Corp. – October 29, 2026) – Greenheart Gold Inc. (TSXV: GHRT) (OTCQX: GHRTF) (the “Company” or “Greenheart Gold”) is pleased to announce that it has received the remaining assay results from the 2026 shallow reverse circulation (“RC”) drilling program at its Majorodam Project in Suriname. The program comprised 147 holes for a total of 10,421 meters (m) and was designed to expand the mineralized envelope around previously intersected gold mineralization at Heuvel West and Heuvel East, and to step out along strike to the north, and included inaugural drill testing of the Gowtu target. Approximately 65% of the results were reported in the Company’s news release dated July 29, 2026. This release completes the reporting of the results from this program, and the significant intervals and hole location data for the entire program are available on the Company’s website (https://www.greenheartgold.com/majorodam).
Highlights
Drill intercepts from this program have extended the Heuvel West zone a further 250 m to the north, taking the total strike extent of Heuvel West to over 1,000 m.
Hole MAJR26-089 which intersected 13.0 m @ 2.84 grams per tonne of gold (g/t Au) (0.30 g/t Au cut-off), including 10.0 m @ 3.54 g/t Au (1.00 g/t Au cut-off) and hole MAJR26-084 which intersected 5.0 m @ 1.74 g/t Au (0.30 g/t Au cut-off) and ended in 3.0 m @ 2.53 g/t Au (1.00 g/t Au cut-off), extending the known mineralization 250 m north from the previously reported intercept in MAJR25-003 (13.0 m @ 4.37 g/t Au).
The inaugural drill testing of the Gowtu target, which lies only 3 kilometers (km) west of the Saramacca mine, included an intercept of 18.0 m @ 0.89 g/t Au (0.30 g/t Au cut-off) in hole MJNR26-068.
Heuvel West Extended 250 m to the North on Three Consecutive Fences
Previously reported drilling confirmed mineralization at Heuvel West in three main zones (north, central, and south) over approximately 800 m of strike length as shown in Figure 1, Figure 2, and Figure 4. The zone had been defined by numerous holes, highlighted by hole MAJR25-003 at the north end, which intersected 13.0 m @ 4.37 g/t Au (0.30 g/t Au cut-off), hole MAJD25-014 in the middle of the trend, which intersected 15.3 m @ 3.72 g/t Au (0.30 g/t Au cut-off), including 8.0 m @ 6.57 g/t Au (1.00 g/t Au cut-off); and hole MAJR25-010 marking the south end of the known trend, which intersected 30.0 m @ 2.06 g/t Au (0.30 g/t Au cut-off) (see the Company’s news releases dated May 7, 2025, November 10, 2025 and February 17, 2026 for all previously reported drill holes referred to above).
The three new drill intercepts from this drill program (which are shown in Table 1 and Figure 1), indicate an extension of the zone of approximately 250 m north of previously reported hole MAJR25-003 (13.0 m @ 4.37 g/t Au), bringing the new strike length to over 1,000 m in length. The new holes include hole MAJR26-089 which intersected 13.0 m @ 2.84 g/t Au (0.30 g/t Au cut-off), including 10.0 m @ 3.54 g/t Au (1.00 g/t Au cut-off), and hole MAJR26-084, which intersected 5.0 m @ 1.74 g/t Au (0.30 g/t Au cut-off) and 3.0 m @ 2.53 g/t Au (1.00 g/t Au cut-off). This lower intercept in MAJR26-084 occurred in the last 3.0 m of the hole. While previous drilling, highlighted in Figure 1 and Figure 2, has outlined mineralized intercepts, it has been a challenge at Majorodam to show consistent continuity between successful drill holes. It is therefore noteworthy that this is the first time that drilling at Majorodam has outlined significant gold intercepts on three consecutive fences.

| Reporting status: Results expressly labelled “previously reported” were disclosed in the Company’s news release dated July 29, 2026; other results are new results reported in this news release. Significant intervals have been calculated using a grade cut-off of 0.30 g/t Au, a minimum length of 5.0 m and a maximum length of 5.0 m of consecutive internal waste. Included intervals have been calculated using a grade cut-off of 1.00 g/t Au, a minimum length of 3.0 m and a maximum length of 2.0 m of consecutive internal waste. Intervals reported at the 1.00 g/t Au cut-off that fall outside a 0.30 g/t Au interval are shown separately. Gold grades are uncapped. Intervals are reported as downhole lengths and true widths are unknown. A full list of collar coordinates is available on the Company’s website (www.greenheartgold.com/majorodam). | ||||||
Gowtu Target – Largely Untested
The Gowtu target in the northwest corner of the Majorodam project area, is about 3.0 km west of Zijin Mining Group’s Saramacca mine, as shown in Figures 3 and 4. The target is defined by an approximately 800 m by 1,500 m gold-in-soil anomaly, which appears to coincide with the north-northwest trending granite/greenstone contact and forms part of a larger soil trend that extends for more than 15 km to the south and encompasses Heuvel West. Trenching programs at Gowtu have been challenging due to the thick colluvial cover in that area. However, trench MJNT25-001 was able to penetrate the colluvium and returned 12.0 m @ 1.04 g/t Au (0.30 g/t Au cut-off). Hole MJNR26-068, which was drilled as part of a fence of 19 RC drill holes to conduct an initial drill test of the Gowtu target, intersected 18.0 m @ 0.89 g/t Au (0.30 g/t Au cut-off) from 5 m downhole. While it is too early to confirm that they are related, the MJNR26-068 intercept lies about 170 m north-northwest of, and potentially along trend with, trench MJNT25-001. These are encouraging initial results given the strategic location of the zone next to Saramacca.
Next Steps at the Majorodam Project
Majorodam is located on the southern limb of the same volcanic trend and regional fold structure that hosts the operating Saramacca deposit, which lies approximately 5 km to the north of the main project area and 3 km to the east of the Gowtu target. The location close to both infrastructure and an existing operating mine greatly reduces the size threshold for what would be a meaningful discovery at Majorodam, compared to a more remote project with little existing infrastructure.
As the Company compiles and reviews the results received from the 2026 drill program, further exploration activities will likely include follow-up drilling on the northern extension at Heuvel West as well as in proximity to the new drill intercept and nearby trench results at Gowtu. In addition, the team will employ its recently acquired TEM geophysics unit as a cost-effective way of gathering more information on the area, and delineating subsurface structures, prior to further drilling. The Company will also compile the results of a soil survey at Majorodam South to determine what the next steps should be for that part of the project area.
Significant Intervals, Sample Collection, Assaying and Data Management
All significant intervals are reported as downhole lengths, and the true widths of mineralization are unknown. Significant intervals in this press release have been calculated using a grade cut-off of 0.30 g/t Au, a minimum length of 5 m, and a maximum length of 5 m of consecutive internal waste. Included significant intervals have been calculated using a grade cut-off of 1.00 g/t Au, a minimum length of 3 m, and a maximum length of 2 m of consecutive internal waste. Gold grades are uncapped.
RC drill samples are collected every meter and weighed in their entirety at the rig side to ensure consistent sample collection, then split, bagged, and tagged. Samples are submitted to the sample preparation facilities of Actlabs and ALS Chemex, both located in Paramaribo, Suriname, while respecting best-practice chain of custody procedures. Samples are dried, crushed to better than 80% passing 2 mm, riffle split (to 500 g), and pulverized to better than 95% passing 105 μm. Coarse blanks are inserted by the Company, and are used between and following suspected high-grade intervals. Barren sand flushes are inserted by Actlabs after each sample is pulverized to clean the bowl, and by ALS Chemex either between batches, when matrix changes are observed, or when compressed air is insufficient. Actlabs’ pulverized samples are transported by Actlabs to their laboratory in Georgetown, Guyana (an ISO 9001 certified laboratory), whilst ALS Chemex pulverized samples are sent to ALS facilities in Peru or Colombia.
Gold assays for the 2026 RC program were carried out using a nominal 50 g fire assay. Actlabs assays were completed with an atomic absorption finish (Actlabs method 1A2), and ALS assays were completed with an ICP-AES finish (ALS method Au-ICP22). Assays with overlimit results are re-assayed with a gravimetric finish (Actlabs method 1A3 for results above 3 g/t Au). Certified reference materials and blanks are inserted at a rate of 5% of samples shipped to the laboratories. RC field duplicates and pulp duplicates are also generated at a rate of 5% of samples. All assay data is subject to QA/QC prior to acceptance into the Company database managed by an independent consultant.
Trench and channel samples collected in 2026 were analyzed by ALS (Au-ICP22). Results from 2024 and 2025 included in Appendix Table A were analyzed by Actlabs (methods 1A2 and 1A3, using a 30 g or 50 g charge), with the exception of diamond drill holes MAJD25-009, MAJD25-010 and MAJD25-011, which were analyzed by Filab Suriname N.V. in Paramaribo using a 50 g fire assay.
