VANCOUVER, Aug. 7, 2018 /CNW/ - Group Eleven Resources
Corp. (TSX.V: ZNG) (OTCQB: GRLVF) ("Group Eleven" or
the "Company") is pleased to provide the results from two
initial drill holes from its Ballinalack zinc-lead project in
Ireland ("Ballinalack" or
the "Project"). Ballinalack is a joint venture between Group
Eleven (60%-interest) and Shenzhen Zhongjin Lingnan Nonfemet
Company Limited ("Nonfemet", 40%-interest), one of the largest zinc
producers in China. The Project is
located 50 kilometres from Boliden's substantial Navan (Tara) zinc mine.
Highlights
- G11-1344-01 is the first ever definitive test of the
Ballinalack fault directly below the historical
estimate1 on the Project; it successfully encountered
the structure, significantly advancing the understanding of local
geometry and helping vector towards four priority Navan Beds
targets
- G11-1344-02, drilled near the south end of the
historical estimate, intersected several zones of significant zinc,
lead and silver mineralization, including:
- 10.3m of 8.9% zinc and 1.7%
lead (10.6% combined) and 52 g/t silver (true width is
estimated at >90%) – drilled within a shallow portion of the
historic estimate (note: silver not previously assayed)
- A second zone of 3.6m of 5.5%
zinc and 0.6% lead (6.2% combined) (true width is estimated at
>90%) – drilled within another portion of the historical
estimate
- New lead-silver intercept in Navan-beds - numerous lead-silver-barite
veins over a length of 29m, including
3.1m of 5.6% lead and 12 g/t
silver (true width estimated at 30%); very high lead to
zinc ratios suggest proximity to a feeder structure
- New intercept of thinner zinc mineralization in the base
of Navan-beds (1.1m @ 4.6% zinc and
0.8% lead, or 5.4% combined, and 12.3 g/t silver; true width
estimated at 30%) – bolstering confidence on a Navan Beds target to
the southeast
"We are thrilled that our bold steps to quickly and efficiently
increase our understanding of the Ballinalack system via our 'Big
Think' strategy are vectoring us towards four priority Navan
Beds targets near the historical estimate" stated Bart Jaworski, CEO. "Importantly, our drilling
suggests historic attempts to test hanging wall Navan Beds targets
at Ballinalack were indeed drilled too far down dip – leaving these
prospective areas virtually untested."
"Additionally, our work is showing that cross-faults may
have a much more significant role in controlling mineralization
than has been previously recognized. This realization has shed an
exciting new light on our emerging Navan Beds targets both
proximally to the historical estimate and regionally on the
property. Lastly, it is gratifying to see our drilling yield robust
silver grades, given a large portion of historically assayed
intervals were run only for zinc and lead."
Further Details on Ballinalack Drilling
The Ballinalack project is unique in Ireland as it is underlain by not one – but
two prospective horizons: the 'Waulsortian' limestone
(hosting the Ballinalack historical estimate and most zinc deposits
in Ireland) and the 'Pale
Beds' (also referred to as 'Navan Beds', which hosts
Boliden's Navan zinc deposit approximately 50 kilometres to the
east). Specifically, Ballinalack is the only known major zinc
occurrence in Ireland that
hosts significant mineralization in both
horizons. The table below summarizes assay results and rock
types from intercepts announced in this press release (see Exhibit
2 for drill hole locations).

G11-1344-01 was diamond drilled to a depth of 625.1m, with an azimuth and dip of 145° and -65°,
respectively (see Exhibit 2 and 3). Key aims were as follows:
- To be the first hole to directly and definitively test the
orientation of the Ballinalack fault directly below the
historical estimate
- To be the first hole drilled obliquely to the historic grid, to
test presence of cross-faults
- To be the first inclined and oriented hole at the
historic estimate, allowing for proper collection of structural
data
- Located proximal and parallel to the only seismic line through
the historical estimate in order to provide geological and
structural information to augment ongoing seismic
interpretation
G11-1344-02 was diamond drilled to a depth of 389.1m, with an azimuth and dip of 170° and -50°,
respectively (see Exhibit 2 and 3). Key aims were as follows:
- To be the second inclined and oriented drill hole at
Ballinalack (after G11-1344-01), allowing for proper collection of
key structural information
- To test a poorly understood area of structural complexity
characterized by several intersecting faults (i.e. including the
Ballinalack fault and several cross-faults)
- To test for mineralization in the Navan Beds below the
Ballinalack Fault
Emerging Navan Beds Targets at Ballinalack
The recent drilling and detailed analysis of historical data has
critically aided Group Eleven's 'Big Think' initiative by
significantly improving the understanding of the Ballinalack
property, notably from a structural framework and Navan Beds
targeting perspective. Although additional work is required to
fully ascertain controls on mineralization, the following can be
stated thus far:
- Exploration for Navan Beds mineralization at Ballinalack is in
its infancy - only 35 holes have historically tested the Pale Beds
in the vicinity of the historical estimate and 16 of them have
returned compelling mineralization
- Four key Navan Beds 'hot spots' are emerging in the vicinity of
the historical estimate (see Exhibit 2)
- These targets are largely defined by encouraging historic
drilling, in combination with newly interpreted
structural/stratigraphic setting, and bolstered by new drill
results in this press release
The following is a brief description of each Navan Beds target
area (see Exhibit 2):
- Target 1 - defined by five historic holes which intersected
significant mineralization (up to 4.0m of 8.4% zinc + lead) within the Navan
Beds in the footwall of the Ballinalack fault. This target is open
predominantly to the north-east.
- Target 2 - also a footwall Navan Beds target, with five
historic holes which intersected significant mineralization
(including 2.7m of 10.1% zinc +
lead). This target spans over one kilometre in strike and is
very sparsely drilled. G11-1344-02 has added further compelling
evidence of mineralization (see Navan Beds mineralization in
Exhibit 1 and Exhibit 2). The northern end of this target was
assayed historically for silver (yielding up to 1.5m of 144 g/t Ag). Strong lead/zinc ratios
and the possibility of relatively enriched silver grades suggests
proximity to a feeder structure. The target is open predominantly
to the south-east.
- Target 3 – defined by an interesting historic (1992) hole which
intersected 4.6m of 5.2% zinc +
lead in the Navan Beds. Four historic follow-up holes drilled
radially 300m away provided a
possible trend to mineralization oriented towards the north-west.
This possible trend may align with a cross-fault adjacent to the
strongest mineralization in the historical estimate. This target is
also compelling as it occurs within the hanging wall of a
postulated major fault recently interpreted from seismic data
by Dr Alastair Beach (see Group
Eleven news release dated January 18,
2018).
- Target 4 – is located within the hanging wall of the
Ballinalack fault and comprises five areas, each bounded by newly
interpreted cross-faults. These targets are especially compelling
given they are situated (i) directly down-throw from known
mineralization (historical estimate), (ii) within very prospective
stratigraphy (i.e. Pale Beds) and (iii) adjacent to the Ballinalack
fault and cross-cutting structures. Areas (a) and (b) are
specifically interesting as a historic (1994) hole in the vicinity
intersected mineralization with visual estimates of 1.0m of 3-4% zinc and a second zone of
4.0m of 1-2% zinc -
representing the strongest hanging wall Pale Bed intercepts on
the property to date. Areas (c), (d) and (e) have never been
drill tested.
Importantly, G11-1344-01 has pinned down the location of the
Ballinalack fault and shown it to be a steep dipping
structure in this area. Historically, it appears cross-faults
were not taken into account and the Ballinalack fault was
interpreted to be much shallower dipping. On this basis, previous
operators drilled two holes, which now appear to have been located
too far down dip to have directly tested the Navan Beds
target. Target 4c, therefore, continues to be a very compelling
area.
Also noteworthy is that the fault block immediately southwest of
Target 4c is now interpreted to have been partially tested by
historic hole B113 (see Exhibit 3). This southern fault block hosts
the weakest-grading portion of the historical estimate. Despite
this, hole B113 still returned highly anomalous mineralization
(1.5m @ 0.7% zinc + lead),
potentially representing the edge of a mineralized zone. Therefore,
this area remains prospective.
Cross-Faults – Regional Significance
Based on drilling and recent analysis of historic data, Group
Eleven believes cross-faults may be much more important in
controlling mineralization at Ballinalack than previously
recognized. This reflects the fact that (i) mineralization appears
to be more proximal to cross-faults than the main Ballinalack
fault; and (ii) the cross-faults at Ballinalack are aligned
parallel to one of the important orientations of mineralizing
structures in Ireland. This
suggests that, within the historical estimate, drilling to test
this prospective geological setting was never done. There are
also significant implications for regional exploration at
Ballinalack.
Outlook
Group Eleven is currently finalizing its detailed half-year work
plan and budget. The key elements from this work are planned to be
disclosed to the market early this Fall. The Ballinalack and
Stonepark projects will continue to remain a focus for this
upcoming period.
About Ballinalack
A historical estimate of 7.7 million tonnes grading 6.3% zinc +
1.0% lead (7.3% combined) was previously disclosed on the Project.
Significant data compilation and verification may be required by a
qualified person before this historical estimate can be classified
as a current resource. A qualified person has not undertaken
sufficient work to classify this historical estimate as a current
resource. The Company is not treating the historical estimate as a
current resource. The historical estimate is described in a report
prepared by the Robertson Group plc in 1991 and is classified under
the "IMM Definition of Terms for Reporting Assets" as an "Indicated
Mineral Resource," using a 4.0% zinc cut-off.

Quality Assurance / Quality Control (QA/QC)
Diamond drill-core described in this press release had a
diameter size of HQ or NQ and recoveries of approximately 90% or
better. Once structural elements were measured from oriented
drill-core, the core was marked-up, logged and photographed on
site. The core was then sawn in half at the Company's core storage
facility with half bagged at average intervals of one-metre and
sent in batches to ALS Minerals' OMAC Laboratory in Loughrea,
Ireland for analysis. Samples were
fine-crushed (CRU-31) to 70% < 2mm and pulverized and
riffle-split to 85% < 75 µm. Zinc, lead and silver assays were
obtained by multi-acid (4-acid) digestion/ICP-AES Package (48
Elements). Analytical accuracy and precision are monitored by the
submission of 3 blanks and 3 standards inserted into the sample
train of 107 samples by Group Eleven personnel. No duplicate
samples were sent to the lab. ALS inserted 11 standards, 6 blank
and ran 10 duplicates as part of their internal QC procedures.
