North River Resources plc ("North River" or the "Company")
Resource expansion drilling programme completed
North River Resources plc, the AIM quoted exploration company,
announces drill results and an assessment of its recently completed
underground diamond drilling programme at the Namib Project in
Namibia.
Highlights
* A total of 4,142 metres of resource drilling completed.
* A number of outstanding intersections continue to support
strong resource upside at Namib, although overall results are not
expected to grow the Indicated Mineral Resources at this stage,
pending further drilling.
* Drill results indicate that refinement of the 3D geological
and structural model is required prior to undertaking further
drilling and that future resource development targeting is
increasingly dependent on accessing additional underground drill
positions as the mine is developed.
* Further to the interim drilling results announced on the 21
March and 26 April 2016, an additional 32 holes, totalling 2,959
metres are being reported in this RNS. Significant intersections of
mineralisation not previously announced, include:
o NLDD072: 3.1m (true width of 2 metres) at 8.2% zinc, 28.4m
(true width of 7 metres) at 33.2% zinc and 7.9m (true width of 3
metres) at 30.6% zinc
o NLDD083: 3.5m (true width of 2.5 metres) at 22.0% zinc and
9.7m (true width of 5 metres) at 18.9% zinc
o NLDDK082: 6.6m (true width of 4 metres) at 20.3% zinc and
10.2% lead
o NLDDK087: 4.3m (true width of 3 metres) at 16.4% zinc
* The Company continues discussions with the Ministry of Mines
and Energy on the grant of the Mining Licence for the Namib Project
and remains hopeful that this will be forthcoming in the near
term.
* Cash preservation remains a priority and the Company has
further reduced corporate overheads and put next step resource
development and drilling plans on hold until there is clarity on
the timing of moving the project forward to a construction
decision.
Details of the completed drilling programme
The drilling programme to test extensions at depth in the North
and South orebodies of the Namib resource, which commenced in
January 2015, has now been completed. A total of 4,142 metres were
drilled, using a contracted Diamec rig together with the Company's
own Kempe drill.
The announcement of additional very encouraging intersections
continues to support the strong resource upside at Namib and
follows previously announced holes from this campaign, including
NLDD067 with 57.1 metres (true width of 8.5 metres) at 28.5% zinc,
and NLDD069 with 35.7 metres (true width of 9.0 metres) at 33.8%
zinc. The overall results of this programme have however been
sporadic and will not at this point translate into a significant
increase in the Indicated Mineral Resource category to underpin an
extension to mine life. The Company has determined that additional
infill and extension drilling is certainly warranted to further
delineate mineralised zones to the level of confidence required to
support Indicated Mineral Resources, but that this should now only
be undertaken following further interpretation of the recently
completed drilling, which will include an update to the geological
and structural model in the light of new data. This drilling
programme has highlighted a greater structural complexity that
needs to be better understood in order to improve future extension
drilling targeting, and that will require ongoing attention if and
when the project is taken forward into construction and mining
operations.
The geological framework model for the deposit continues to
indicate there is no reason to suggest that mineralisation does not
continue at depth, but these drilling results show that zone
targeting and delineation remains challenging due to the
sub-vertical lode geometry and limits of available drilling
positions from which to optimise intersection angles. The Company
remains confident in the upside of the Mineral Resource, as
indicated by both the deep drilling intersections achieved during
this latest drilling campaign, and previous down-hole
electromagnetic surveying work (see press release of 6 September
2013) projecting potential mineralisation conductors to depths as
far as 700 metres below surface. In the short term the Company has
put drilling on hold until there is clarity on the timing of moving
the project forward to a construction decision, and will
concentrate on additional data re-analysis and collection from
available drill core, review and interpretation of recent drilling
data, and refinements to the 3D model using all available
information to improve understanding of the geological
structure.
Mining licence and ongoing development
"The Company continues to discuss the granting of the mining
licence for the Namib Project with the Ministry of Mines and
Energy, and is in the process of providing further detail to
support the proposal submitted to the Ministry in April 2016 on
meeting the new Mining Licence conditions.
Cash preservation remains a priority and the Company has further
reduced corporate overheads and put next step resource development
and drilling plans on hold until there is clarity on the timing of
moving the project forward to a construction decision. A lower run
rate level of expenditure going into 2017 will extend the available
timeframe for the Company to firm up a development plan for the
Namib Project or redefine the corporate strategy.
Competent Persons Statement
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 commented, "These drill results
provide further confidence in the potential to grow the Namib
mineral resource but at the same time have highlighted the
challenges to achieving a step change increase in resource until a
construction decision is taken and the mine is further developed
during ongoing operations".

* Represents holes forming part of this drilling campaign that
have been reported previously in the interim announcements of 21
March 2016 and 26 April 2016
Significant Intercepts are based on the following criteria:
-- Minimum intercept length: 3 metres
-- Maximum internal waste: 1 metres
-- Cutoff Lead/zinc 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.
Appendix: Quality Assurance Quality Control of assay results
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.
Samples were prepared and analysed at Bureau Veritas Namibia
(Swakopmund). Iron, lead and zinc samples were fused with sodium
peroxide, dissolved in dilute HCL and analysed by Inductively
Coupled Plasma (ICP) Optical Emission Spectrometry. Silver samples
were dissolved in a multi acid digest and assayed by inductively
Coupled Plasma (ICP) Optical Emission Spectrometry.
The Quality Assurance Quality Control (QAQC) programme included
blanks and certified reference materials (CRMs) from African
Mineral Standards (AMIS) in Johannesburg, South Africa and
duplicate samples. QAQC results were monitored and where issues
were noted, the laboratory was requested to re-assay the affected
samples.
During the QAQC analyses for the results reported in Table 1
above, sporadic failures in the zinc, lead and silver CRMs and
blanks were noted. The lab was requested to re-assay these affected
QC sample as well as ten samples either side for the failed
elements. Failures were either resolved or understood after
re-assay.
