Potential for Non-Cyanide Gold Recovery Confirmed at Panorama Ridge
Vancouver, B.C. – George Sanders, President of Goldcliff Resource Corporation (“Goldcliff” or the
“Company”) (GCN: TSX.V, GCFFF: OTCBB PINKS), reports that recent metallurgical test work by
Dundee Sustainable Technologies (CSE: DST) indicates that gold mineralization from Panorama
Ridge may be amenable to Dundee’s patented CLEVR™ non-cyanide gold recovery process.
Initial results are encouraging. Testing of York-zone drill core achieved 88% gold recovery using
the CLEVR process with a thermal oxidation pre-treatment. While these results are preliminary and
additional test work and optimization will be required, management considers the outcome positive
enough to continue evaluating this innovative and environmentally responsible processing option.
In September, several drill-core samples representing a range of grades, lithologies, and
mineralized zones were collected from Panorama Ridge. Six samples from the York zone—grading
from 0.2 g/t Au to 2.5 g/t Au and spanning two lithologies—were crushed and blended into a
composite grading 0.74 g/t Au. Following thermal oxidation, the composite tested at 0.71 g/t Au.
After one hour of CLEVR leaching, an 88% gold recovery was recorded.
Dundee explains in their report to Goldcliff that a key feature of the CLEVR process is its closed-
circuit, zero-effluent design. The solid residue produced is inert, sulphide-depleted, and non-acid-
generating. A Toxicity Characteristic Leaching Procedure (“TCLP”) completed on the residue
confirmed that all monitored elements were below TCLP thresholds. By removing the requirement
for cyanide and avoiding the need for a conventional tailings pond, CLEVR offers the potential for
lower environmental risk and a reduced surface footprint.
Dundee has recommended additional laboratory work to better define material concentration
behaviour, pre-treatment requirements, and gold recovery characteristics. Goldcliff anticipates
continued collaboration with Dundee Sustainable Technologies as it works to further evaluate the
potential of the Panorama Ridge gold project.
