Ximen Mining Corp (CVE:XIM) (OTCQB:XXMMF) has updated investors further on construction of the new portal at its historic Kenville gold mine project in British Columbia and also reported on new metallurgical test results on material from the site.
The firm is currently refurbishing the mine's existing portal so it can access mineralization, which was outlined in the resource estimate of 2009.
"Work on the 257 portal continued with excavation of overburden to expose the portal rock face," said Ximen in the statement on Friday.
"Timber and steel sets will be installed prior to placement of the new portal steel culvert. Finally, the overburden will be backfilled around the portal culvert. After the new portal has been established, the underground workings will be accessed."
The firm also said it had received a final report on metallurgical test work completed by a lab in Langley in the Canadian province, which showed high-grade recovery and that Kenville material is suitable for gravity-flotation processing at a facility such as the nearby Greenwood mill of Golden Dawn Minerals.
A 10 kilogram (kg) sample was ground and subjected to a single-stage Falcon gravity concentration test, Ximen said.
It was then panned and determined to recover 39.3% of gold at a grade of 11,225 grams per ton (g/t), while a silver recovery of 8.6% silver at a grade of 4,577 g/t was achieved.
A 2 kg subsample of the gravity tailings was also subjected to rougher flotation, which achieved an additional overall gold recovery of 59.7% and an additional silver recovery of 86.4% in a mass yield of 15%, the firm also noted.
Updating on the permitting process for the new decline at the Kenville mine, Ximen said the authorities have now requested that the firm begin public notification under the Environmental Management Act.
Approval of the new underground development program is anticipated once this process and other information has been submitted as part of the final submission, said Ximen.
The mine in the Nelson camp reportedly produced 65,236 ounces of gold and 27,686 ounces of silver between 1889 and 1956.
