Carlyle Recovers 80% Gold in Preliminary Newton Metallurgical Testing
Vancouver, British Columbia--(Newsfile Corp. - March 1, 2024) - CARLYLE COMMODITIES CORP. (CSE: CCC) (FSE: BJ4) (OTC Pink: CCCFF) ("Carlyle" or the "Company") is pleased to announce positive results from recent preliminary metallurgical test work on its Newton Gold & Silver Project, with gold extraction of approximately 80%.
Metallurgical Testing Summary:
The Company submitted a master composite consisting of primarily felsic volcanic material of continuous drill core intervals from three drill holes for testing, which is the primary host rock of the Company's current National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") Newton Project Inferred Mineral Resource. Testing was carried out and supervised by Base Metallurgical Laboratories (BaseMet), Kamloops, B.C. under test program BL1338. The objective of the program was to conceptualize a preliminary process flowsheet that would produce gold and silver doré, and to evaluate the metallurgical performance of the mineralization. The testwork included gravity concentration, Whole-ore-leach (WOL) and flotation at various grind sizes followed by leach of the rougher concentrate and tailings.
Gravity Test Results
Two initial gravity concentration tests were conducted on the master composite at 80% passing (P80) 75 and 150 microns. The highest recovery was at the coarser grind size with approximately 22.8% of the gold being recovered at a grade of 211.8 g/t.

Initial Whole Ore Leach ("WOL") Test Results
A preliminary WOL investigation was completed at three grind sizes. The results for the master composite tested showed that a primary grind size in the range of P80 75 microns provided the best results with 73.2% of the gold and 43.2% of the silver extracted. To investigate the gold losses, a 3-Stage Diagnostic leach test was completed on Test 3 WOL tailings. The results indicated that some of the gold may be locked in sulphide minerals and gangue requiring additional liberation.

Flotation + Leach Results
To provide better liberation and improve overall gold extraction a flotation/leach flowsheet was tested. The flotation results were encouraging with 88.5% of the gold and 82.6% of the silver recovered to a rougher concentrate. The rougher concentrate was reground to approximately P80 15 microns prior to a 2-hour pre-oxidation and 48-hour cyanide leach. The rougher tailings were leached at the target primary grind of P80 75 microns and achieved the best gold extraction after 24-hours. The overall gold and silver extraction for the master composite was 80.3% and 32.7%, respectively.

About the Newton Project
The Newton Project is a 100% owned Gold and Silver Project near Williams Lake, British Columbia, encompassing more than 24,000 ha.
- The Newton Project contains a current National Instrument 43-101 ("NI 43-101") Resource Calculation which utilizes optimized pit shell constraints to fulfil the requirement for "reasonable prospects for eventual economic extraction". The inferred mineral resource contains 861,400 oz of Au, and 4,678,000 oz of Ag with an average grade of 0.63 g/t Au, a cut off of 0.25 g/t Au throughout 42,396,600 tonnes.
- The Newton Gold Project is a large, bulk tonnage, low - to intermediate-sulphidation, epithermal gold deposit with nearly 35,000 m of drilling exploring and developing the historical resource, primarily between 2009-2012.
- Gold and associated base metal mineralization is precipitated in extensive zones of strong quartz-sericite alteration as well as in mafic volcanic and clastic sedimentary rocks and along fault and fracture zones.
- Underlying the deposit, a large IP anomaly measures 4 km x 2 km and covers an area greater than 7 km2 - yet the existing inferred mineral resource occupies slightly over 0.5 km2 or just 7% of the anomaly.
- The system remains open in multiple directions and is workable year-round.
