Further Significant Channel Sampling Results at New Departure Silver Mine, Montana
Black Mountain Resources Limited (LSE:BMZ), the silver focused development company with interests in the US, has announced that further high grade silver results have been returned from channel at its New Departure Silver Mine in Montana.
Highlights:
* Second round sampling results surpass expectations with Ag 90 oz/t (2,550 g
/t) plus over 0.5-2m channels (see highlights in table 1 and full results)
* Key samples confirm proposed run of mine grade and key production
assumptions
* Grades confirm earlier high grade sampling programmes and extend the Main
Zone silver mineralisation
* Hard Rock Consulting (`HRC’) has taken historical sample data and recent
underground sample results to construct a model of the silver vein
mineralisation (see Fig 1) to confirm the historical resource estimates and
update the mine plan for New Departure
* HRC is also incorporating zinc and lead as saleable products from the New
Departure Mine
* Results highlight that the Blue Dot level has the largest potential for
hosting a mineral resource in the downward and northwest plunging remainder
of the ore body as well as confirming existing historical results
* A third and final round of underground sampling and drilling is planned in
September to expand high grade zones in historical workings and a drill
possible extension zones in the Blue Dot level Main Zone
Black Mountain Chairman, Pete Landau, said:
“These high grade sampling results once again confirm the quality of this silver asset, which will be the first of our three assets to be brought into production upon completion of financing. We believe that this will be forthcoming in the near term and accordingly, HRC is constructing a model of the silver vein mineralisation to confirm the historical resource estimates and to develop a preliminary mine plan for New Departure. Notably, these grades of up to 90 oz/t of silver confirm the proposed run of mine grade and key production assumptions, which holds us in good stead as we continue to tread the path towards transforming Black Mountain into a low cost, high grade silver producer in the near-term.”
Sampling Process:
28 samples were delivered to Osborn, Idaho for sample preparation and assay by American Labs. All samples were taken from the Blue Dot Level at New Departure. A Thermo Scientific Niton XL3 XRF instrument was used extensively to check for zinc grade in the Blue Dot Level. This instrument will be used in future sampling and drilling programmes to validate high zinc zones.
