North River Resources plc ("North River" or the "Company")
Drilling campaign successfully delineated additional extensions
of known lodes
and identified additional high grade targets
North River Resources plc, the AIM quoted resource company
focused on the Namib Lead-Zinc Project in Namibia ("Namib" or the
"Project"), wishes to provide an update on its drilling campaign,
since the previously announced JORC compliant mineral estimate in
August 2014
Highlights
- 4,828 metres drilled since August 2014
- Results provide management with further confidence in the
previously announced JORC compliant Mineral Resource Estimate
- Delineated extensions of known lodes and high grade targets
indicated by significant intersections including:
o NLDDK070: 3.6m @ 15.6% Zn, 1.0% Pb
o NLDDK071: 7.3 @ 14.9% Zn, 3.2% Pb & 4.5m @ 9.3% Zn, 13.6%
Pb
o NLDD062: 3.8m @ 10.9% Zn, 8.7% Pb
o NLDD061: 5.7m @ 16.8% Zn, 6.9% Pb
o NLDD056: 8.7m @ 9.6% Zn, 3.7% Pb,
- Resource expansion drilling campaign announced on 19 November
2015 underway; the targeting of drill holes is informed by the
results of the infill drilling campaign. Results of the resource
expansion drilling will be released in due course.
Detail
As previously announced, North River has been undertaking a
drilling campaign at the Namib Lead-Zinc project. Since the last
Mineral Resource Estimate (MRE) of August 2014, a total of, 4828
metres of drilling have been completed in 66 holes. Of these, 52%
(34 holes) had significant intercepts, see details in Table 1.
The drilling campaign focussed primarily on targeting both new
extensions of known mineralised shoots, as well as infill drilling
to potentially convert Inferred Mineral Resources into the
Indicated Mineral Resource category. Drilling was undertaken mainly
in the top half of the North Orebody and also below the historic
South Mine, which is around 200m below surface. The majority of the
Company's current Inferred Mineral Resources lie below the South
Mine, which is also referred to as the Southern orebody (see
figures in appendix). In general, the drilling results in both
areas have met management's expectations and increased its
confidence in the Mineral Resource.

Drilling below the Junction stope, and between
the Junction and the Central stopes of the Southern
orebody targeting resource expansion, has yielded
encouragingly high grade results:
* NLDDK070: 3.6m @ 15.6% Zn, 1.0% Pb
* NLDDK071: 7.3 @ 14.9% Zn, 3.2% Pb & 4.5m @ 9.3% Zn,
13.6% Pb
* NLDD062: 3.8m @ 10.9% Zn, 8.7% Pb
* NLDD061: 5.7m @ 16.8% Zn, 6.9% Pb
* NLDD056: 8.7m @ 9.6% Zn, 3.7% Pb

* Holes reported in MRE update of 19 September 2014, but true
widths have been updated to reflect the current geological
interpretation
** Geotechnical holes drilled and not sampled.
Significant Intercepts are based on the following criteria:
-- Minimum intercept length 3 m
-- Maximum internal waste 1 m
-- Cutoff Pb/Zn combined 1 %
-- True thickness lengths were obtained by measuring intercepts
manually from a perpendicular-to-dip sectional review. Lengths are
approximate due to the variable nature of the lodes.
Diamond core samples were half core samples and are selectively
sampled based on observable sulphide mineralisation. Approximately
one metre of waste is sampled either side of mineralisation. RC
drill holes were sampled on one metre intervals and was half-split
using a riffle splitter to collect a 2 - 2.5 kg sample that was
sent for analysis.
Samples were prepared and analysed for iron, lead and zinc (as
well as As, Ca, Co, and Cu) at Bureau Veritas Namibia (Swakopmund).
They were fused with sodium peroxide, dissolved in dilute HCL and
analysed by Inductively Coupled Plasma (ICP) Optical Emission
Spectrometry. Sample pulps were sent from Bureau Veritas to the
Inspectorate of Metals and Minerals, Rustenburg, South Africa for
silver analysis (as well as Bi, In, Sb and Sn) using a mixed acid
digest (including Hydrofluoric, Nitric, Hydrochloric and Perchloric
Acids) with an Inductively Coupled Plasma (ICP) Mass Spectrometry
finish. Silver assay results are pending and will be reported once
they are received.
The Quality Assurance Quality Control (QAQC) programme included
certified reference materials (CRMs) from African Mineral Standards
(AMIS) in Johannesburg, South Africa; blanks and duplicate samples.
QAQC results were monitored and where issues were noted, the
laboratories were requested to re-assay the affected samples. The
metal values in the above table have all passed the QAQC process,
although batches from drill holes NLDD054, NLDD055, NLRC110,
NLRC111, NLRC112, NLRC113, NLRC114, NLRC120 and NLRC121 were
re-assayed due to QAQC failures in the original assaying. Silver
values have not been reported at this stage due to problems with
the ICP MS machine at the Inspectorate delaying the re-assay of
affected silver samples (which originally failed the QAQC
process).
Drilling already completed helps to inform the targeting of the
3,800m resource expansion drilling campaign that is currently
ongoing and which was announced by the Company on 13 November 2015.
This resource expansion drilling campaign is targeting
mineralisation below the Northern part of the existing orebody as
well as the Southern part.
The Company is targeting the release of an updated JORC (2012
Edition) resource statement by the end of the second quarter of
2016, which will include all the drilling done after the last MRE
update and the current resource expansion drilling campaign.
As previously announced, the Company received from the Ministry
of Mines and Energy in Namibia a Notice of Preparedness to Grant
the mining licence for the Namib Lead and Zinc Project subject to a
number of conditions. The Company has until the 28(th) February
2016 to accept the Notice and then 60 days to submit proposals in
relation to these licence conditions. The proposals need to be
agreed with the Ministry ahead of the issue of the mining licence.
The notice is dated 28 January 2016 and more details pertaining to
that can be read on the Company website.
As per the requirements of the disclosure of Exploration Results
under JORC (2012 Edition), JORC Table 1 can be found at the
following link:
http://www.rns-pdf.londonstockexchange.com/rns/7809O_2-2016-2-11.pdf
The information in this release that relates to Exploration
Results is based on information compiled by Mr. Galen White,
Principal Geologist of CSA Global (UK) Ltd and a Competent Person
who is a Fellow of the Australasian Institute of Mining and
Metallurgy (FAusIMM). Mr White has sufficient experience which is
relevant to the style of mineralisation and type of deposit under
consideration and to the activity being undertaken to qualify as a
Competent Person as defined in the 2012 Edition of the
"Australasian Code for Reporting of Exploration Results, Mineral
Resources and Ore Reserves. Mr. White consents to the inclusion in
this release, of matters based on his information, in the form and
context which it appears.
North River CEO, James Beams, said, "I am encouraged that the
results of the drilling have confirmed previous drilling and I am
very pleased to share the high grade drill results from the
Southern orebody. I look forward to providing regular updates on
the resource expansion drilling campaign and other pre-construction
work streams over the coming months".
