CANEX REPORTS CYANIDE SOLUBLE GOLD RECOVERIES OF 94 to 99% FROM
BOTTLE ROLL TESTS AT GOLD RANGE, ARIZONA
DRILL RIG MOBILIZING
Calgary, Alberta - CANEX Metals Inc. (“CANEX” or the “Company”) is pleased to announce
exceptional cyanide soluble gold recoveries from bottle roll test work on mineralized samples
from the Gold Range Project, Arizona.
Highlights
- Metallurgical test work on 8 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 6 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 mineralization is well suited for heap leach recovery.
- A drill rig is being mobilized to the project and drilling should commence shortly.
Dr. Shane Ebert, President of the Company stated, “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. We are very encouraged to see exceptional recoveries from throughout
the mineralized 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 mineralized 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
mineralization. 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 7 to 64 metres 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.

Sodium cyanide and lime consumption where well within acceptable levels at 0.24 to 0.32 kg/t
and 0.7 to 1.5 kg/t, respectively . All of the samples were found to be non- refractory and
appear to contain fee milling gold. The samples display rapid leach kinetics, with the majority
of gold extracted within the first 6 hours and maximum extraction almost complete within 24
hours.

The results confirm that the mineralized 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 mineralization.
Drill Program Update – RC Drilling About to Commence
A track mounted reverse circulation drill rig is currently being mobilized to the Gold Range
Project. An announcement will be made once drilling has commenced. This third round of
drilling will consist of approximately 50 drill holes and in excess of 3000 metres and will focus
on stepping out and expanding new gold discoveries and testing new targets.
About CANEX Metals
CANEX Metals (TSX.V:CANX) is a Canadian junior exploration company focused on
advancing its Gold Range Project in Northern Arizona. Led by an experienced management
team, which has made three notable porphyry and bulk tonnage discoveries in North America,
CANEX has identified and tested several targets which host the potential for bulk tonnage
oxide gold mineralization at its Gold Range Project. Recent drilling has identified ne ar surface
bulk tonnage gold potential along a recently identified trend extending from the Eldorado to
Excelsior Zones. Hole GR21- 37 from Excelsior returned 1.6 g/t gold over 35.1 metres
including 8.2 g/t gold over 4.6 metres. These new discoveries occur along a 3 kilometre long
highly prospective mineralized trend that has seen limited modern exploration.
The Company remains focused on testing and advancing key exploration targets on the Gold
Range Property through continued exploration and drilling.
