RC Drilling Intersects one of Widest and Highest Grade-Thickness Intercepts to Date at the Boin Gold Deposit

VANCOUVER, British Columbia, Sept. 17, 2026 (GLOBE NEWSWIRE) — Newcore Gold Ltd. (“Newcore” or the “Company”) (TSX-V: NCAU, OTCQX: NCAUF) is pleased to announce additional drill results from the 80,000-metre drill program underway at the Company’s Enchi Gold Project (“Enchi” or the “Project”) in Ghana. Reverse Circulation (“RC”) Drilling at the Boin Gold Deposit (“Boin”) encountered a wide zone of higher-grade gold mineralization within the lower oxidized and upper fresh mineralization. Hole KBRC411 intersected 2.59 grams per tonne gold (“g/t Au”) over 69.0 metres (“m”) from 58 m, including 6.41 g/t Au over 24.0 m from 59 m. This intercept is one of the widest and highest grade-thickness zones encountered at Boin to date. Drilling continues to demonstrate the continuity of gold mineralization and potential for reserve and resource growth, as well as higher-grade mineralization, at Enchi. Results from drilling completed in 2026, including drilling targeting higher-grade mineralization at depth, are expected to be incorporated into future project economic studies and may support further mine plan optimization.

Highlights from RC Drilling at the Boin Gold Deposit at Enchi

  • Drilling intersected high-grade gold mineralization above the mineral reserve grade.
    • Hole KBRC411 intersected 2.59 g/t Au over 69.0 m from 58 m, including 6.41 g/t Au over 24.0 m from 59 m.
    • This intercept is one of the widest and highest grade-thickness zones encountered to date at Boin.
  • Drilling targeted shallow mineralization within the central portion of the deposit.
    • Hole KBRC414 intersected 0.83 g/t Au over 32.0 m from 70 m, including a higher-grade interval of 3.37 g/t Au over 6.0 m from 84 m.
    • Drilling supports future mine plan optimization, with drilling continuing to delineate Enchi’s higher-grade potential.
  • Drill results not included in Mineral Resource Estimate and Pre-Feasibility Study, with drilling continuing to highlight Enchi’s longer-term prospectivity.
    • Drilling reached a maximum vertical depth of 125 metres, with the average vertical depth of all holes drilled to date at Boin only down to 100 metres.
    • All deposits at Enchi remain open for expansion along strike and to depth.

Luke Alexander, President and CEO of Newcore stated, “We are excited to continue to delineate Enchi’s higher-grade potential. This drilling includes one of our best intercepts encountered to date on the Project, as well as a wide zone of above reserve grade gold mineralization. This drilling continues to demonstrate the opportunity for future mine plan optimization and the potential to incorporate additional higher-grade mineralization into future studies. With the drill rigs turning at site, we look forward to continuing to unlock the value potential of our Enchi Gold Project in Ghana.”

RC Drilling at the Boin Gold Deposit
KBRC395, KBRC396, KBRC404 and KBRC411 to KBRC414 (7 RC holes totalling 960 m) were completed at Boin, targeting shallow mineralization within the central portion of the deposit. The goal of this drilling was reserve conversion for future mine plan optimization, with a focus on converting higher-grade portions of the deposit. Drilling was designed to improve geological confidence and confirm grade continuity, supporting future reserve and resource updates. This drilling focused on targeting oxidized and shallow fresh mineralization, and reached a maximum vertical depth of 125 metres. The holes reported in this news release were distributed across 5 separate sections spread along a 1.9 km strike length.

The drilling reported in this news release targeted the central portion of the Boin Gold Deposit. Hole KBRC411 intersected a wide, high-grade, gold mineralized zone with 2.59 g/t Au over 69.0 m from 58 m, including 6.41 g/t Au over 24.0 m from 59 m. This is one of the widest and highest grade-thickness intercepts encountered to date at Boin. This hole was drilled in an area of known mineralization with a goal of better defining the higher-grade targets at Enchi, highlighting the potential for future mine plan optimization. Hole KBRC414, collared 100 metres south of KBRC411, also encountered a wide zone of mineralization with 0.83 g/t Au over 32.0 m from 70 m, including a higher-grade interval of 3.37 g/t Au over 6.0 m from 84 m. Hole KBRC404, located 500 metres south of KBRC411, intersected 0.68 g/t Au over 22.0 m from 70 m, including 1.64 g/t Au over 7.0 m from 72 m.

RC drilling completed at Boin continues to intersect mineralization above the reserve and resource grade and continues to confirm continuity along strike and down dip, defining and extending the principal structures which comprise the Boin Gold Deposit.

Enchi Work Program
An 80,000 metre drill program is underway at Enchi. The drill program is focused on resource conversion, resource growth and discovery. RC drilling is targeting near-surface mineralization (oxide, transition, and shallow fresh mineralization) focused on resource conversion and continuing to define the potential for reserve and resource growth along strike at existing deposits. Diamond drilling is targeting the high-grade potential at depth. The completed first phase of the drill program was infill drilling for resource conversion, with only the first 28,000 metres of the drill program incorporated into an updated Mineral Resource Estimate announced on March 18, 2026 that formed the basis for a Pre-Feasibility Study (“PFS”). All deposit areas and pre-resource targets at Enchi remain open along strike and at depth, providing for future resource growth across the district-scale property.

Development work continues at Enchi, in support of project advancement, including metallurgical testwork, hydrogeological testing, geotechnical work, and environmental work. A Pre-Feasibility Study was completed in June 2026 (see news release dated June 24, 2026), outlining a base case assessment of developing an open pit, standard milling and carbon-in-leach operation using contract mining and processing 5.5 Mtpa. Recent drilling completed at Enchi has highlighted potential for resource growth, with high-grade encountered at depth and mineralization delineated below the pits that constrain the current Mineral Reserve and Mineral Resource Estimates. Drill results reported in 2026 have not been included in the Mineral Resource Estimate and PFS.

Boin Gold Deposit
Boin is one of the four deposits which comprise the Mineral Reserve Estimate and Mineral Resource Estimate at Enchi (Boin has a Probable Mineral Reserve of 15.9 million tonnes grading 0.84 g/t Au containing 429,000 ounces; an Indicated Mineral Resource of 23.5 million tonnes grading 0.73 g/t Au containing 550,000 ounces; and an Inferred Mineral Resource of 9.2 million tonnes grading 0.60 g/t Au containing 178,000 ounces). Boin is located 10 kilometres south of the town of Enchi, with nearby roads and power and further access provided by a series of drill roads. Boin is outlined on surface by a greater than six-kilometre-long by up to one-kilometre-wide gold in soil anomaly. An airborne geophysical anomaly coincident with the Boin structure extends for a further kilometre north and three kilometres south beyond the limits of current drilling. To date, approximately 40% of the gold-in-soil anomaly at Boin is untested by drilling, with the average vertical depth of all holes drilled to date at Boin only down to 100 metres.

VANCOUVER, British Columbia, Sept. 17, 2026 (GLOBE NEWSWIRE) — Liberty Gold Corp. (TSX: LGD; OTCQX: LGDTF) (“Liberty Gold” or the “Company”) is pleased to report results from its Phase 6 metallurgical test program on the Black Pine Oxide Gold Project (“Black Pine”) in southeast Idaho. This pre-production validation test work was conducted at the Reno laboratory of Kappes, Cassiday & Associates (“KCA”), using bulk column leaching (column dimensions 4 feet (“ft”) diameter by 20 ft high) on seven run-of-mine (“ROM”) sized samples (with particle sizes ranging from 2” to 8” P80), weighing approximately 10 to 15 tonnes each.

These columns are intended to simulate gold leach performance within a commercial ROM heap. The term “ROM” herein refers to blasted ore taken directly from the open pit and placed onto the heap leach pad without crushing, agglomeration or mechanical stacking, using a simple haul truck dump and dozer push/rip approach.

Gold extractions from the bulk column leaching program confirm the previously modeled gold leach recoveries for ROM-sized material at Black Pine. These findings validate key gold recovery assumptions incorporated into the Preliminary Feasibility Study (“PFS”) and updated in the recently released Feasibility Study (“FS”) results for Black Pine (see press releases dated October 10, 2024, and September 8, 2026).

Further, all metallurgical test work to date measuring gold extraction through leaching across a wide range of particle sizes (P80 ranging from fine (75 microns) to coarse (8 inches or ~200 millimeters)), consistently supports the economic viability of processing Black Pine ores through a ROM heap leach operation.

Jon Gilligan, President and CEO, Liberty Gold, commented, “At Black Pine, we’re conducting the detailed metallurgical work that many heap leach projects overlook. This is part of our disciplined, technical approach to the study phase and it will materially de-risk delivery as we move towards a construction decision. By validating gold leach extractions across the full range of particle sizes, we are optimizing the balance between mining costs and ultimate gold recoveries. These results confirm that our gold recovery models for ROM material are reliable and consistent. They provide additional confidence that predicted gold recoveries can be achieved through a simple, low-cost ROM processing strategy.”

Highlights

  • Gold Extraction Insensitive to Particle Size: The modest improvement in gold extraction from coarse to fine particle size does not justify the cost of crushing. On average, for the material types tested, reducing the rock particle size from 10” to 1” increases gold extraction less than 3%. This relationship is characteristic for some Carlin-style oxide ores and this test work adds further validation to the weight of evidence from the extensive metallurgical test programs carried out by the Company over the last 8 years, which strongly indicate minimal value uplift from crushing or blasting to a finer particle size.
  • Modeled Recoveries Corroborated at Coarse Particle Sizes: The bulk column results confirm recoveries modeled at ROM particle sizes and provide additional confidence in the gold recovery predictions using FS metallurgical models going into detailed engineering design. Of particular note are the results from a) the Discovery upper Pola sample, which is indicative of early leach feed ore under the FS mine plan and performed within 0.5% of modeled gold recovery, and b) the gold extraction results from the Rangefront Ppos sample, which outperformed modeled gold recoveries by over 13%.
  • Rapid Leach Kinetics Validated: Black Pine is emerging as a classic example of oxide ores where ROM gold extractions are rapid and relatively insensitive to particle size. On average, 90% of total gold extraction was achieved within 36 days of leaching, with several columns reaching the same milestone in 22 days or less. The commercial implication of this feature of the Black Pine ores is low cost ounce production with significant operational flexibility on the leach pad.
  • Demonstrated Reagent Consumption: Cyanide reagent consumption measured in crushed-rock laboratory column tests is typically higher than commercial-scale ROM heap leach operations and therefore requires scaling assumptions for financial modeling. Both cyanide and lime consumption values from bulk column testing demonstrate expected commercial-scale performance and have underpinned FS reagent consumption estimates. This information de-risks an important operating cost that is traditionally poorly predicted, creating increased technical confidence in process operating cost estimates.
  • Favorable Permeability Results: Compacted permeability results for six of the seven ROM-sized samples tested show adequate solution percolation up to 150 meters (“m”) of simulated compaction. This contributes to a large data set at Black Pine showing that managed blending of select ores will maintain permeability within the heap leach pad. This is beneficial not only for ultimate gold recovery, but also for geotechnical stability of the heap leach facility. One sample underperformed as predicted due to high clay content. This material would be identified as clay with the current modeling methodology and blended as required on the heap.

Richard Zaggle, Senior Director, Mining and Metallurgy, Liberty Gold, commented, “Rangefront contains oxide ore with favorable leach characteristics, while also offering low processing costs. The bulk column program significantly strengthens an already extensive metallurgical column leach data set for Black Pine ores, with multiple variability columns delivering more than 90% gold extraction at laboratory particle sizes between 1 and 3 inches. Test extractions at this level, without crushing, are rare.”

Phase 6 Metallurgical Test Summary

The Phase 6 program was designed to validate modeled gold leach recoveries at coarse particle sizes to support a ROM heap leach processing route for Black Pine ores.

The Phase 6 program tested seven Black Pine ores, collected with an excavator (~20 tonnes per sample), six taken from historic pits and one taken off the surface (see Figure 1). Metallurgical composites were made up from bulk samples and leached at particle sizes ranging from a P80 of 75 microns up to ROM-size (8”). Larger particle size material was leached in bulk columns (dimensions 4’ diameter by 20’ high). These columns are much larger than a typical column test (see Figure 2) and are intended to simulate gold leach performance in commercial scale ROM leach pads.

Figure 1 – Summary Map of Black Pine Metallurgical Program Sample Locations

Figure 1

Figure 2 – Bulk columns (ROM Sizing) vs. normal columns and general difference in top size for particles

Figure 2

Seven samples were tested under standard test conditions for Black Pine oxide gold material, with results summarized below in Table 2. The average weighted gold extraction for the bulk columns was 72.4%, which is in line with modeled recoveries in the recent FS. All of the bulk column results fell within previously modeled recovery ranges, with the exception of Rangefront, which over-performed.

Two results are of particular note:

  1. The Rangefront Ppos sample had the highest extraction tested at 95% for a 0.43 g/t gold head grade. This recovery is high for material at this gold grade and is considerably in excess of modeled recovery for the Ppos unit in Rangefront, even at finer crush sizes. The result may have significant implications for increasing the value of Rangefront as the Ppos unit is currently viewed as low value stripping material in the recently published FS.
  2. The I-pit Pold sample extraction at 51.9% was an expected result as this rock unit is known to have lower gold extraction and the results are aligned with modeled recoveries.

It should be noted that columns which met or over-performed versus the modeled predictions are representative of a greater portion of the recoverable ounces within the resource, notably the larger mining phases at Black Pine, Discovery and Rangefront.

Table 1 shows results from the Phase 6 test work program with extraction results for all samples. Results include fine bottle rolls, coarse bottle rolls, small columns, and the bulk columns.

Black Pine ROM Modeling Methodology

The metallurgical database at Black Pine comprises more than 200 column leach tests on composite material sampled from large diameter (PQ) drill core and nine (9) bulk samples (3 by Noranda and 6 by Liberty Gold in 12’’ diameter columns at a P80 between 2 and 3 inches). In typical metallurgical test programs for new oxide gold deposits, gold extractions are tested at a variety of particle sizes ranging from very fine (P80 of 75 microns) to relatively coarse (P80 of 1”). Particle sizes significantly larger than 1” are generally not tested as sampling and testing is cumbersome and expensive. Liberty Gold has adopted and implemented an industry-proven approach using laboratory bottle roll and column leach protocols to accurately project commercial gold and silver recoveries at any particle size from laboratory data. An example of this methodology can be seen in Figure 3 and Table 2.

Figure 3 and Table 2 – An example of the methodology used across Black Pine to predict recovery at larger particle sizes than tested in laboratory conditions. This plot is for the B-pit sample (ROM Pilot #4).

Figure 3 and Table 2

The Company took the view that laboratory bulk column testing was an important de-risking step for new production planning, despite having commercial information from the historic operations at Black Pine, where ~30 million tonnes of ROM-sized ore was heap leached in the 1990’s.

Detailed Results

Extraction versus time graphs illustrate both the leach kinetics (rapid leaching rate in first 10 to 30 days) and relative extraction performance over the leach cycle for the seven bulk samples (see Figure 4).

Silver

Bulk column leach tests recorded silver (“Ag”) extractions up to 39%, with a weighted average Ag recovery of 21%. These silver grades and extractions are generally above previous variability composite averages and will be incorporated into future Ag recovery model updates to support prediction of silver production once the silver resource model is completed.

Ongoing Metallurgical Programs

Liberty Gold has an ongoing pre-production metallurgical program for Black Pine:

  • Phase 8: Composites from 24 sonic drill holes (~1,400 meters) in the legacy heap leach pad are being tested for economic potential. Vat leach tests have been completed and a second round of column leach testing, Phase 8B, has started at KCA in Reno. Results are expected in H1 2027.
  • Phase 9: Phase 9 involves a re-assay campaign of ~2,000 samples for LECO and Preg Rob focused on better understanding dilution risk with MET4 and Poc materials. Management considers current dilution assumptions to be conservative. These assays are pending and will be used to guide mining decisions in detailed engineering and future mine planning.
  • Phase 10: 26 composites from additional core holes in Rangefront are being tested at KCA with a focus on all grade ranges across the primary gold hosting units in Rangefront. Results are expected in H1 2027.   This program is focusing on increasing variability sample coverage in Rangefront.
  • Phase 11: This program is focused on low grade samples (<0.1 g/t) across the deposit in order to improve the low-end gold extraction model. Results are expected in Q1 2027.
  • Phase 12: Phase 12 will be focused on understanding potential extractions of waste dump material. This program will begin following completion of RC drilling currently happening on site.

These additional phases of work will continue to validate the feasibility level gold and silver recovery models. Further test work will be completed as needed to ensure model accuracy through detailed design and into production.

Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources

The information, including any information incorporated by reference, and disclosure documents of Liberty Gold that are filed with Canadian securities regulatory authorities concerning mineral properties have been prepared in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of United States securities laws.

Without limiting the foregoing, these documents use the terms “measured resources”, “indicated resources”, “inferred resources” and “mineral reserves”. These terms are Canadian mining terms as defined in, and required to be disclosed in accordance with, NI 43-101, which references the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards, adopted by the CIM Council, as amended. However, these standards differ significantly from the mineral property disclosure requirements of the United States Securities and Exchange Commission (the “SEC”) in Regulation S-K Subpart 1300 (the “SEC Modernization Rules”) under the United States Securities Act of 1934, as amended. The Company does not file reports with the SEC and is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards.
