Greenheart Gold Confirms Gold Mineralization
at Majorodam and Provides an Exploration and
Project Update
Diamond drilling at Majorodam, Suriname confirms the presence of a mineralized zone at
least 800 m long at Heuvel Main in addition to a second zone at Heuvel East.
Greenheart Gold has entered into an option to acquire a 100% interest in the Gold Hill
project in Guyana, and drops options on its Tamakay and Abuya projects.
A 3,000 m trenching program has commenced on the Tosso Creek project in Suriname.
Longueuil, Québec--(Newsfile Corp. - November 10, 2025) - Greenheart Gold Inc. (TSXV: GHRT)
(OTCQX: GHRTF) (the "Company" or "Greenheart Gold") is pleased to provide an update on the
inaugural diamond drill program at its Majorodam project in Suriname, an update on exploration at its
Tosso Creek project in Suriname, and updates on its exploration portfolio in Guyana. At Majorodam,
which lies only 8 kilometers (km) south of Zijin's Saramacca mine, a satellite mine to Zijin's active
Rosebel gold mine and mill, Greenheart Gold recently completed an 11-hole diamond drill program
which totalled 2,335.6 meters (m). The program was designed to follow up and provide important
additional geological and structural information on the four encouraging intercepts from Greenheart
Gold's initial reverse circulation (RC) drilling completed in Q1 2025 and follow up on previously
announced trench results. Two or three holes were drilled around each of these targets and results
confirmed the presence of a North-South trending gold mineralized system at Heuvel that extends for at
least 800 m as well as a second mineralized zone approximately 500 m east of the Heuvel Main zone
called Heuvel East.
Highlight results from the program can be seen in Figure 1 and Table 1, along with the previously
released results from the RC hole and trench results. Hole MAJD25-011 was drilled approximately at the
mid-point of the Heuvel Main Zone and intersected approximately 50 m below the previously reported
trench MAJT25-029 that had intersected 18.0 m @ 6.39 grams per tonne of gold (g/t Au). MAJD25-011
intersected 11.5 m grading 1.34 g/t Au, including 5.0 m grading 2.77 g/t Au.
Hole MAJD25-002 was drilled at the southern end of Heuvel Main at an oblique angle to hole MAJR25-
010 and intersected 12.3 m grading 0.82 g/t Au, including 5.5 m grading 1.58 g/t Au. Hole MAJD25-005
was drilled at the north end of Heuvel Main, twinning hole MAJR25-003, and intersected 5.0 m grading
1.77 g/t Au.
Hole MAJD25-006, drilled as a twin hole to the previously reported RC hole MAJR25-015 intersected
13.0 m grading 1.29 g/t Au, including 5.5 m grading 2.3 g/t Au. This area, Heuvel East, lies 900 m east
of the main zone and is associated with a gold in soil anomaly that extends approximately 500 m in
length.
While gold mineralization in drill core was confirmed by at least one hole in each of the four target areas,
the grade and tenor of some of the diamond drill intercepts did not match that of the targeted RC and
trench results. The Company believes that the indicators of a mineralized system are present at
Majorodam, although the structural controls on gold mineralization are more complex than the initial
interpretation had suggested. Greenheart Gold's analysis of results, combined with structural
measurements from drill core and detailed mapping (supported by high-resolution drone magnetics)
indicate that gold mineralization may be controlled by shallow plunging fold hinges deformed within a
north-south shear at the Heuvel Main zone. This interpretation is similar to those presented by others
exploring the same greenstone belt in Suriname where drill orientations have played a crucial role in
defining volumes of gold mineralization. The diamond drill rig remains at Majorodam and the Company
intends to re-commence drilling to test the updated geologic model before the end of November.
Tosso Creek Update
Exploration at Greenheart Gold's Tosso Creek project in Suriname continues to advance with infill soil
sampling at a 400 m by 50 m sample spacing. Results from the soil program to date are shown in Figure
2, and continue to define several large gold anomalies, the largest extending over 5 km in length with
widths of up to 500 m. This extensive soil anomaly aligns with the orientation of the volcano-sedimentary
units located in the west and northwest of the project area, in addition to anomalies found along the
granite contact that runs strikes northeast in the south. An excavator has been mobilized to the project
and has commenced a 3,000 m trenching program over the strongest soil anomalies. In addition, a Lidar
survey has been completed, and a high-resolution drone magnetics survey is anticipated to be
completed by year end. Based on successful results, the Company would expect to commence drill
testing in the first half of 2026.
Gold Hill, Guyana
The Company recently entered into an option agreement with arms' length third parties to acquire a
100% interest in the Gold Hill project in Guyana. The project is located approximately 13.5 km east of
Aris Mining Corporation's Toroparu project, on which a Preliminary Economic Assessment was
released in October 2025 outlining a gold deposit containing 5.3 million ounces (Moz) of gold (Au) in
measured and indicated resources and 1.2 Moz Au of inferred resources. The Gold Hill project consists
of mineral rights covering an area of approximately 40 square kilometers in the Mazaruni mining district
in north-western Guyana. The project area is deformed around a dolerite intrusion and appears to have
been subjected to multiple deformation events and exhibits similar open folding to that observed at the
nearby Toroparu deposit. The presence of multiple gold bearing vein systems on the property suggests
a strong likelihood of hydrothermal alteration related to mineralizing fluids. The presence of artisanal
saprolite and alluvial mining at the project area provides further evidence of the gold mineralization in the
area.
Termination of the Tamakay and Abuya Option Agreements
At the Tamakay project in Guyana, the programs carried out by the Company included detailed mapping,
276 grab samples and 7,794 soil samples. In addition, 7,606 m of trenching was completed in areas of
interest uncovered by the initial programs. These activities were also supported by 85 line-km of ground
based magnetic surveys and 50 line-km of gradient array Induced Polarization survey (IP). Following this
activity, the Company completed a 1,473 m diamond drilling program to test several known occurrences
of high-grade quartz veins, which have been the subject of historic artisanal mining activity. The drill
program confirmed the high-grade nature and continuity of some of these veins; however, the intercepts
in general were relatively narrow and showed little evidence of gold mineralization in the wall rock or the
presence of more extensive sheeted type of vein system. The Company believes that the density of
veining and the extent of gold mineralization are insufficient to suggest potential for an economic deposit
of the size and scale required to justify development in such a remote area and has therefore elected to
terminate its option with the various property owners.
At Abuya, after approximately 12 months of exploration work, the Company completed detailed mapping
along with collecting 2,798 soil samples and 295 grab samples over the project area. Areas of interest
arising out of these programs were followed up by 3,263 m of trenching and channel sampling with no
meaningful results being reported. After completing these programs, the Company did not feel that the
targets warranted follow-up drilling and has therefore also decided to drop its option on the project.
The acquisition of Gold Hill and the dropping of Tamakay and Abuya are consistent with Greenheart
Gold's strategy to quickly assess projects and to be in a position to drill prospective targets in a 10 to
12-month timeframe or alternatively move on from projects that don't meet expectations and replace
these with new opportunities. The Company feels that this strategy will continue to provide the highest
possible chance of exploration success.
Sample Collection, Assaying and Data Management
Significant intervals in this press release have been calculated using a grade cut-off of 0.3 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 1.0 g/t Au, a minimum length of 3 m, and a
maximum length of 2 m of consecutive internal waste. Gold grades are uncapped and mineralized
intersection lengths are not necessarily true widths. 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. Diamond drill core samples consist of half of either HQ or NQ core taken continuously at regular
intervals averaging 1.4 m, bagged, and labelled at the site core shed. Samples are submitted to either
Actlabs or Filab laboratories, both located in Paramaribo, Suriname, while respecting best-practice
chain of custody procedures. Samples are dried, crushed to 80% passing 2 mm, riffle split (to either 250
g or 500 g), and pulverized to 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 the
analytical laboratory after each sample is pulverized to clean the bowl. Actlabs' pulverized samples are
transported by labs to their laboratory in Georgetown, Guyana (an ISO 9001 certified laboratory), whilst
Filab pulverized samples remain in Paramaribo for analysis. In both cases, gold assay is carried out
using a 30 g or 50 g fire assay with an atomic absorption finish. Assays with overlimit results are re-
assayed with a gravimetric finish. Certified reference materials and blanks are inserted at a rate of 5%
of samples shipped to the laboratories. RC field duplicates pulp duplicates are also generated at a rate
of 5% of samples. All assay data is subject to QA/QC prior to accepting into the Company database
managed by an independent consultant.
