• Highlights from recent drilling on the Majorodam Project in Suriname include hole D-014 at Heuvel West, intersecting 15.3 m @ 3.72 g/t Au (inc. 8.0 m @ 6.57 g/t Au) in addition to hole D-013-W1 intercepting 6.0 m @ 3.04 g/t Au.

Longueuil, Québec--(Newsfile Corp. - February 17, 2026) - Greenheart Gold Inc. (TSXV: GHRT) (OTCQX: GHRTF) (the "Company" or "Greenheart Gold") is pleased to provide an update on its Majorodam exploration programs, including drill results from its most recent 10-hole, 1,055-meter (m) Phase 2 diamond drill program that was completed in mid-December 2025. This program was designed to test the controls on the structurally complex mineralization encountered in the 11-hole, 2,311 m Phase 1 diamond drill program completed in September 2025 (see the Company's press release dated November 10, 2025) and the initial 2,138 m, 20-hole reverse circulation ("RC") drill program that was completed in March 2025 (see the Company's press release dated May 7,2025). Greenheart Gold is also pleased to announce a new zone at Majorodam called the Gowtu zone, which lies in the northwest corner of the project area and is shown on Figure 1. The zone of anomalous gold in soil that is associated with Gowtu also appears to be part of the soil anomaly that is present at Heuvel West. Combined, the soil anomaly extends over 15 kilometers (km) along the granite/greenstone contact south of the Heuvel West Target to the north end of the Gowtu Target. The Company is announcing a 10,000 m RC drill program to follow up on these targets.

Heuvel West

Greenheart Gold's Phase 2 diamond drill program at Majorodam, which was aimed at providing additional structural and geologic information on the mineralization controls at Heuvel West and East, returned five significant intercepts from eight holes as outlined in Table 1. Table 2 includes all collar coordinates for drillholes completed to date on the project. Heuvel West lies within a series of interbedded volcanics and sediments hosting gold mineralization within a north-south trending high strain corridor and coincident north-south fold axes. Highlight intercepts from the recent diamond drill program include hole D-014 which assayed 15.3 m (downhole) grading 3.72 grams per tonne of gold (g/t Au), including 8.0 m grading 6.57 g/t Au, and Hole D-013-W1 which intersected 6.0 m grading 3.04 g/t Au, including 5.0 m grading 3.46 g/t Au, and hole D-011, which intersected 11.5 m grading 1.34 g/t Au, including 5.0 m grading 2.77 g/t Au.

Heuvel West has been intersected in three main areas by drill intercepts as shown in Figure 2 and Figure 3, which confirm a zone of drill intercepts over approximately 800 m in strike length. Drilling at Heuvel West to date has been concentrated over these three areas of the target and Heuvel West remains open to infill drilling as well as to expansion to both the north and south. A cross section showing interpreted geology and the location of significant intervals is shown in Figure 4.

Gowtu

The Gowtu Target (see Figure 1) represents a newly defined zone that lies in the northwest corner of the project area and is defined by a moderate to high grade northwest-southeast trending gold in soil anomaly of approximately 800 m x 1,500 m. Gowtu is located 3 km to the west of the Saramacca mine (see Figure 1) and looks to be closely associated with the westerly granite/greenstone contact trending NNW-SSE. Exploration of this target to date includes two phases of soil sampling, detailed mapping, LiDAR, a pre-existing airborne magnetic and radiometric survey and more recently trenching (results pending). Gowtu has never been drill tested to the Company's knowledge.

Heuvel East

Heuvel East lies approximately 500 m to the east of Heuvel West, as shown in Figure 2. Heuvel East was identified by an area of high-grade soil results and subsequently confirmed by three drillholes, one from each drill program, including hole D-019 from the most recent drill program, which intersected 7.8 m grading 1.56 g/t Au (see Tables 1 and 2). Previously reported holes that intercepted Heuvel East were D-006, which intersected 13.0 m grading 1.29 g/t Au, including 5.5 m grading 2.30 g/t Au and R-015, which intersected 40.0 m grading 1.49 g/t Au. While the soil anomalies to the north and south of the drillholes appear sparse, subsequent investigation of the soil cover in these areas shows that much of the area could be covered by transported material. As a result, the target is being interpreted as remaining open to both the north and south.

Drill Plans

Greenheart Gold intends to initiate follow-up drill programs shortly on the Heuvel West, Heuvel East and Gowtu Targets. The drill programs are expected to total approximately 10,000 m. The RC drill program will aim at both expanding and infilling the Heuvel West Target and expanding the Heuvel East Target. Drilling will target areas between existing drill intercepts at Heuvel West and will step out to the north and south at Heuvel East, where gold anomalism may be masked by a detrital ferricrete cover (hardened paleo-colluvium likely derived from adjacent elevated duricrust ridges). The scout RC drill program proposed for the Gowtu Target is designed to confirm the results from the soil survey where trenching has proved ineffective due to potential colluvium cover and to begin to test the continuity of the 15 km gold in soil anomaly.

Significant Intervals, Sample Collection, Assaying and Data Management

All significant intervals are reported as downhole lengths, and the true thickness of mineralization is unknown. In this press release significant intervals 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. 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 on-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 Actlabs to their laboratory in Georgetown, Guyana (an ISO 9001 certified laboratory), whilst Filab pulverized samples remain at their Paramaribo laboratory (ISO 9001:2015 certified) 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 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.

About Greenheart Gold Inc.

Greenheart Gold is an exploration company that builds on a proven legacy of discoveries within the Guiana Shield, a highly prospective geological terrain that hosts numerous gold deposits yet remains relatively under-explored. The Company is led by former executives and members of the exploration group of Reunion Gold, a team that was most recently noted for the discovery and delineation of the multimillion-ounce Oko West deposit in Guyana. Greenheart Gold intends to build on its technical knowledge, strong contact base and previous success from exploring in the Guiana Shield to assemble, maintain and explore a portfolio of early-stage exploration projects in Guyana and Suriname that are prospective for orogenic gold deposits.
