NEWCORE GOLD ANNOUNCES AVERAGE GOLD RECOVERY OF 91.9% FROM BULK-SCALE PILOT HEAP TESTS AT THE ENCHI GOLD PROJECT, GHANA

Newcore Gold Ltd. has released positive results from two bulk-scale pilot heap tests completed as part of the continuing metallurgical program at the company's 100-per-cent-owned Enchi gold project in Ghana. Two bulk-scale pilot heap tests, leached for 60-days, were completed on 15-tonne composite samples of oxide mineralization from the Sewum Gold Deposit ("Sewum") and the Boin Gold Deposit ("Boin") at Enchi. An average gold recovery of 91.9% was achieved from both samples, with Sewum achieving an average gold recovery of 93.5% and Boin achieving an average gold recovery of 90.3%. These strong metallurgical results on oxide material from Enchi continue to highlight the Project's amenability to heap leach processing.

Highlights from the Pilot Heap Test Results

Average gold recovery of 91.9% achieved from testwork on oxide mineralization.

Two 15-tonne composite samples from Sewum and Boin, leached for 60-days.

Sewum sample achieved an average gold recovery of 93.5% with a head assay grade of 0.81 grams per tonne gold ("g/t Au").

Boin sample achieved an average gold recovery of 90.3% with a head assay grade of 1.09 g/t Au.

Representative samples were collected at Sewum and Boin from two trenches on the central portions of each deposit, completed specifically for metallurgical testwork.

The Sewum and Boin Gold Deposits at Enchi comprise approximately 76% of the Mineral Resource Estimate defined to date at Enchi.

Results continue to show low consumption values for reagents: cement, cyanide, lime.

Results in-line with column testwork completed to date, highlight +90% gold recoveries with oxide and transition material amenable to heap leach processing.

The pilot heap test results confirm the results of 14 column tests of 60 days or longer, completed over the past two years, which returned an average gold recovery of 92.2%.

Additional metallurgical testwork underway

Optimization work continues with additional column tests to be completed on oxide mineralization from the Sewum, Boin, Nyam and Tokosea gold deposits.

Additional testing of sulphide mineralization from Sewum is in progress.

Greg Smith, VP Exploration of Newcore stated, "These bulk-scale pilot heap tests completed on representative oxide material from the Enchi Gold Project returned high recoveries, in-line with results from metallurgical testing completed to date, further supporting the amenability of Enchi to heap leach processing. The larger, 15-tonne samples are a significant step in confirming the positive results from the extensive lab testing completed to date. These results, along with the additional positive test results completed and reported since 2021, will be incorporated into our updated Preliminary Economic Assessment Study which is targeted for completion in H1 2024. This testwork was completed on samples from the two largest deposits currently identified on the Project, Sewum and Boin, which together compromise approximately 76% of the current Mineral Resource Estimate. We continue to de-risk and advance the development of the Project with further metallurgical testwork underway on both oxide and sulphide mineralization at Enchi."

Metallurgical Testing Summary

The two bulk-scale 15-tonne pilot heap tests on oxide mineralization were completed as part of the ongoing metallurgical program at the Company's 100%-owned Enchi Gold Project in Ghana. A gold recovery of 93.5% for Sewum and 90.3% for Boin was achieved after 60 days of leaching.

The gold recovery increased rapidly for the first 20 days reaching 78.6% for Sewum and 73.2% for Boin, continued at a moderate rate until day 40 reaching 91.7% for Sewum and 85.9% for Boin, with ultimate recoveries of 93.5% for Sewum and 90.3% for Boin achieved after 60 days.

Head Sample Analysis

The mineralized material collected from the trenches was mixed in an agglomeration drum, with three representative sub-samples taken at regular intervals. The head assay data for the three sub-samples is presented in Table 2. The average assay for the Sewum mineralized material was 0.81 g/t Au and that for Boin was 1.09 g/t Au.

Reagent Consumption

The samples showed low reagent consumptions, in-line with the column testwork completed to date. During agglomeration, 8 kg/t of cement was added for each 15-tonne bulk sample. Cyanide consumption averaged 0.74 kg/t (0.77 kg/t for Sewum and 0.71 kg/t for Boin) with a 2.28 kg/t lime (hydrated) addition to maintain a pH above 10.5 for both tests.

Metallurgical Testing - Pilot Heap Tests

The two 15-tonne samples were transported to the University of Mines and Technology located in Tarkwa, Ghana.

Two platforms were built to receive the bulk-scale metallurgical samples. Each of the two samples received were blended in an agglomeration drum and sub-samples taken for head assays. 8 kg/t of Portland cement, 1000 ppm cyanide solution and 2.28 kg/t lime were used in the agglomeration process and the agglomerates were placed on the prepared platforms. After a curing period of 72 hours, irrigation began and was completed for 60 days.

The heap leach pad preparation commenced with compaction of the ground with an impermeable clay layer at a slope angle of between 3 and 6 degrees near the designated collection solution point. The ground compaction was done such that there was uniform strength across the ground to prevent point stresses that could puncture the impervious membrane. Primary berms of height 0.5 metres were constructed around each leach pad, approximately 1.0 metre away from the heaps. The space that was occupied by the mineralized material was approximately 2.5 x 2.5 metres and was covered with quartz pebbles to create channels for the solution to run through the heap and then flow without obstruction to the collection point. 15-tonnes of each of the two different mineralized materials, one from Sewum and one from Boin, were then agglomerated on site with the aid of a concrete mixer. Coarse material larger than 5 to 10 cm was crushed, otherwise the mineralized material was agglomerated as received and poured out and heaped manually. The cyanide solution was pumped into the dripper tubes that were laid on top of the pilot heaps, for discharge onto the prepared heaps. Dripper tubes were used to prevent splashing of cyanide solution beyond heaps as an environmental precaution. Percolated solution then flowed down the pad slope to the collection point where the solution was channelled into a container filled with activated carbon for gold adsorption. Solution samples were then taken before and after adsorption for Atomic Absorption Spectrophotometry ("AAS") analysis to determine the gold in solution for metal balancing and recovery calculations. After adsorption, the solution was conditioned and recirculated onto the heaps (closed circuit) for 60 days.

At the end of each processing day, solution exiting the heap was collected, the volume measured and the gold in solution determined. Gold in all particulate samples was analysed by fire assaying and that in solution samples by AAS.

The objective of the pilot heap tests was to simulate the response to leaching of the samples with the emphasis on establishing the gold dissolution characteristics (rate and extent) and reagent consumption within the material. All samples showed amenability to heap leaching, with recoveries from samples from both Sewum and Boin averaging 91.9% after 60 days.

Boin and Sewum Oxide Sample Details

The material for the pilot heap tests was sourced from two trenches excavated for metallurgical testwork on the Enchi Gold Project. The locations of the trenches were selected in order to allow for wide gold mineralized intercepts of oxide gold mineralization in each of the two largest deposits, Sewum and Boin. Material exposed in the trenches is consider representative of the oxide portion for both deposits. A total of 61 metres was completed on KBTR_MET_001 from Boin and 107 metres was completed on SWTR_MET_001 from Sewum. Trench KBTR_MET_001 at Boin was dug-out manually while as SWTR_MET_001 was dug-out mechanically. Samples were assigned a new unique number and submitted to the Intertek Lab located in Tarkwa, Ghana.

Trench KBTR_MET_001 at Boin includes a mineralized interval of 1.43 g/t Au over 44 metres, with a 15-tonne composite sample prepared from one 30-metre-long segment consisting of 30 one-metre samples with an average grade of 1.22 g/t Au (ranging from 5.17 g/t Au to 0.05 g/t Au).

Trench SWTR_MET_001 from Sewum includes a mineralized interval of 1.18 g/t Au over 92 metres, with a 15-tonne composite sample prepared from three segments totalling 60 metres in length and comprised of 60 one-metre samples with an overall average grade of 0.83 g/t Au (ranging from 5.31 g/t Au to 0.17 g/t Au).

Enchi Gold Project - Comparison of Pilot Heap Test Results to Column Test Results

The positive gold recovery values (average recovery of 91.9%) from the bulk-scale pilot heap testwork confirm results from a series of column tests completed over the last two years. A total of 14 column tests with leach times of over 60-days have been completed, with an average gold recovery of 92.2% achieved. This column testwork included six tests with a 60-day duration, two tests with a 70-day duration, and six tests with a 90-day duration. Gold recovery curves were similar with average gold recoveries of 65.6% after 30 days, 85.6% after 60 days, and 92.2% at the completion of the tests. The tests were completed on oxide and transition material from the Sewum and Boin deposits, except for one sample completed on mixed oxide and transition material from the Kwakyekrom gold deposit. Material used for the testwork included reverse circulation chip coarse rejects, split diamond drill core, as well as trench samples. Consumption values for reagents (cement, lime, cyanide) are similarly low when comparing the results of the column tests with the pilot heap test results. All testwork was completed at labs located in Tarkwa, Ghana, with thirteen of the column tests completed at Intertek Lab and one completed at the University of Mines and Technology.
