Further Significant Channel Sampling Results at New Departure Silver Mine,
Montana
Black Mountain Resources Limited (ASX | AIM: BMZ), the silver focused
development company with interests in the US, is pleased to announce that
further high grade silver (`Ag') results have been returned from channel
sampling at its New Departure Silver Mine in Montana.
A full pdf version of this announcement including images is available from the
company's website at www.blackmountainresources.com.au.
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.
Highlights of the sample results are listed below. Note that silver results are
given in ounces per ton and length in centimetres. Full details of the sampling
results are provided in Annexure A.

gold focused development company focussed on the advancement of three highly
prospective previously operating assets located in two of the world's most
developed and proven silver and gold mining regions of Idaho and Montana, USA.
The Company holds a 70% interest in the New Departure Silver Project, the
Conjecture Silver Project and the Tabor Gold and Silver Project pursuant to 45
year leases from Chester Mining Company, Lucky Friday Extension Mining Company
and Brush Prairie Minerals respectively. Black Mountain plans to implement low
cost production and development programmes across all three assets. It is also
implementing exploration programmes to capitalise on the exploration upside
potential apparent across its portfolio.
