Obtains Cyanide Soluble Gold Recoveries Up To 99% From Bottle Roll Tests
CANEX Metals Inc. (TSXV: CANX) has achieved exceptional cyanide soluble gold recoveries from bottle roll test work on mineralised samples from the Gold Range Project, Arizona.
- Metallurgical test work on eight bottle roll samples from the Gold Range Project achieved final cyanide soluble gold recoveries ranging from 94 to 99%, averaging 97%.
- The test work showed rapid leach kinetics with the majority of gold extracted within the first six hours, and maximum extraction almost complete within 24 hours.
- Sodium cyanide and lime consumption are well within acceptable levels and the overall results indicate Gold Range gold mineralisation is well suited for heap leach recovery.
- A drill rig is being mobilized to the project and drilling should commence shortly.
“The bottle roll samples were mainly taken from the Eldorado and Excelsior Zones and represent a range of gold grades from varying depths in the system,” President, Dr Shane Ebert, said.
“We are very encouraged to see exceptional recoveries from throughout the mineralised zone, demonstrating the system could be amenable to heap leach processing and significantly de-risking the bulk tonnage heap-leach exploration concept at Gold Range.”
Bottle Roll Test Work
Eight samples of mineralised reverse circulation drill cuttings from the Gold Range Project were submitted to SGS Laboratories in Burnaby British Columbia for bottle roll testing to better understand the cyanide soluble gold recovery and leach characteristics of the Gold Range mineralisation.
Four of the samples were from the Eldorado zone, three samples were from the Excelsior zone, and one sample was from the Contact Zone located between Eldorado and Excelsior. The samples represent low grade gold mineralization (0.2 g/t gold), intermediate grade mineralization (0.5 to 0.8 g/t gold), and higher-grade zones (2 to 3.4 g/t gold) and were from a range of depths from seven to 64m down hole.
Each sample was air-dried then crushed to 100% passing 10 mesh. A 1 kg charge from each sample was subject to standard leach conditions (cyanide concentration of 0.5 g/L NaCN with 48 hour retention time) and assayed at 0, 2, 6, 24, and 48 hours.
The results confirm that the mineralised zones recently discovered at the Gold Range project are well suited to heap leach extraction methods and reinforces the Company’s objective of exploring for and defining zones of bulk tonnage gold mineralisation.
RC Drilling About to Commence
A track mounted reverse circulation drill rig is currently being mobilised to the Gold Range Project.
This third round of drilling will consist of approximately 50 drill holes and in excess of 3000m and will focus on stepping out and expanding new gold discoveries and testing new targets.
