Tertiary Minerals plc said that drill results had to date failed to show significant mineralisation at depth at the North Ruth target in the Pyramid silver-gold project in Nevada, USA.
PROGRAMME
The company conducted soil and rock chip sampling and trenching throughout 2021 which established “wide intervals of significant silver and associated gold mineralisation” at surface at North Ruth across a 500-metre zone.
In February 2022, Tertiary excavated additional trenches and in early March completed reverse circulation (RC) drilling, comprising six holes for 1,050m (3,445 ft), to explore the potential continuation of the mineralisation at depth.
LOCALISED SUPERGENE
“We executed a limited and cost-effective drill programme, utilising RC, to determine if the
mineralisation is present at depth but the results have been disappointing,” said managing director Patrick Cullen.
“A detailed analysis of the results will be needed before any further exploration is undertaken.
“Indications are that localised supergene enrichment of silver has resulted in the grades observed at surface.”
OTHER PROJECTS
Mr Cullen added that permitting was progressing at the Brunton Pass copper project, also in Nevada, where the company expects to resume activities.
Tertiary has also started field work on the Jacks copper project in Zambia and expects to begin drilling in late April or early May 2022.
