ELN Jan 16 2013
January 16, 2013, Vancouver, BC;
El Nino Ventures Inc. ("ELN" and the
"Company") (TSX.V: ELN; OTCQX: ELNOF
Frankfurt: E7Q) is pleased to announce
the results from Phase 1 metallurgical
testwork commissioned by its partner,
Votorantim Metals Canada Inc.
(Votorantim), on samples from the Murray
Brook polymetallic deposit, located in
the Bathurst Mining Camp, New Brunswick.
The purpose of the testwork was to
investigate flotation options for
sequential recovery of copper, lead and
zinc concentrates from Murray Brook
feed.
The metallurgical testwork was completed
at RPC Science & Engineering
Laboratories (RPC) in Fredericton (New
Brunswick), under the direction of
metallurgists Ross Gilders and Leo
Cheung. Further information on RPC may
be found at the laboratories' website at
http://www.rpc.ca
Results
Testwork was completed on bulk drill
core samples from the Eastern Zone and
from the Western Zone of the Murray
Brook deposit (Figure 1; Table 1). The
test program consisted of sample
preparation and compositing,
characterization, and batch flotation
tests followed by locked cycle tests on
a composite sample. The composite sample
head grade for the testwork is similar
to the grade of the current high
confidence Measured resources for Murray
Brook.
Locked cycle tests by RPC successfully
produced individual copper, lead and
zinc concentrates with the following
recoveries and grades (Table 2):
- Recoveries of 51.4% copper, 1.7%
zinc, 4.5% lead, and 12.5 % silver
in a copper concentrate
grading 17.5% copper, 6.0% zinc,
6.2% lead, and 591 g/t silver;
- Recoveries of 36.6% lead, 7.2%
copper, 1.4% zinc, and 17.5% silver
in a lead concentrate grading
50.3% lead, 2.4% copper, 5.3% zinc,
and 833 g/t silver; and
- Recoveries of 88.8% zinc, 15.8%
copper, 8.3% lead and 25.3% silver
in a zinc concentrate grading
53.8% zinc, 0.5% copper, 1.1% lead,
95 g/t silver.
A copy of the report is available for
viewing on the
Company's website. Additional
metallurgical work has been commissioned
by Votorantim and RPC, which involves
completing expanded and extended locked
cycle tests to optimize copper, lead and
precious metal recoveries in support of
a planned Preliminary Economic
Assessment in 2013.
Harry Barr, Chairman & CEO states: "The
results of the Phase 1 metallurgical
testwork on Murray Brook are
encouraging, particularly the 89% zinc
recovery combined with good silver
recovery. These initial metallurgical
results plus the results of 18,500
metres of drilling completed since 2011
and the resource estimation of February
2012, confirm the robustness of Murray
Brook as this well-located project is
steadily advancing towards the planned
completion of a Preliminary Economic
Assessment in H1 2013."
Sampling
The sample materials were derived from
three HQ size drill cores (Table 1).
Hole MB-2012-121 was drilled in the
Eastern Zone, the shallower and more
copper-rich of the two massive sulfide
zones at Murray Brook. Holes MB-2012-124
and MB-2012-132 were drilled in the
deeper, more zinc-lead-precious metal
rich Western Zone. (Description and
assay results for each of the three
holes are provided in ELN press releases
dated July 30, August 14, August 28,
2012). The drill core was logged, split,
sampled and shipped to RPC. Intervals of
potential secondary mineralization and
fracturing were sampled separately. In
total 3226 kg of material was delivered
to RPC for testwork.

Grindability Tests
Composite samples for each of the three
Murray Brook drill holes were submitted
for grindability test work. Rod Mill
Grindability Indices for the Murray
Brook bulk sample materials averaged
14.6 kWh/t with a hardness percentile of
55%. Bond Ball Mill Grindability Indices
averaged 10.7 kWh/t with a hardness
percentile of 10%. These data suggest
that Murray Brook mineralization is of
moderate hardness for a rod mill and
lower hardness for a ball mill.
Mineralogy
SEM-EDS mineralogical studies of the
overall composite sample and each
individual drill core by RPC indicate
that sphalerite and galena occur as
interstitial grains, inclusions,
veinlets and attachments to pyrite.
Chalcopyrite occurs as interstitial
grains to pyrite. Chalcopyrite is less
common hole MB-2012-132, consistent with
the lower copper grades in the Western
Zone. Covellite is present in
MB-2012-124. Generally, the principal
silver mineral is tetrahedrite. The
sulfide grains are mainly <20 ñm in
size. However, sphalerite grains 50-100
ñm in size are present interstitial to
pyrite grains.
Flotation
Primary bulk sulfide rougher floats were
carried out to estimate flotation
performance. The reagent regime included
400 g/t CuSO4, pH 10.0-10.5, 33.3 g/t
3418A, 10g/t PAX, 15 g/t MIBC and 11
minutes total at 1250 rpm. Rougher
target liberation grind size was
established to be D80 of ~30 ñm. Initial
testwork found that flotation
performance was adversely affected by
the presence of secondary (oxidized)
material. This latter material therefore
was excluded from the overall composite
sample used in locked cycle testing.
Next Steps
Additional metallurgical testwork is
planned to be carried out by RPC in
early 2013. The results will be reported
in a planned Preliminary Economic
Assessment to be completed in Q1 2013.
The additional testwork will focus on
optimizing copper, lead and precious
metal recoveries, in part through
processing of larger samples in bigger
equipment. An expanded metallurgical
test program, including pilot plant
testing, may be warranted if PEA studies
are positive.

About El Niño Ventures Inc. Bathurst
Projects
El Niño Ventures Inc. has two active
projects in the Bathurst Mining Camp;
- Murray Brook Project
The Murray Brook project is a
polymetallic, massive sulfide
deposit and is the fifth largest
deposit discovered to date in the
Bathurst Mining Camp, New Brunswick.
The Murray Brook property is located
60 km west of Bathurst. It is
supported by excellent
infrastructure, including paved
roads, grid electricity and
communities to provide goods,
services and skilled labour.
A $3 million exploration budget
was approved for the 2012
exploration program. It included
$2.5 million for drilling to bring
resources into the measured category
at the Murray Brook deposit and
$500,000 for exploration of the
Murray Brook and Camel Back
properties, both of which are
covered by the option agreement with
Murray Brook Minerals. To date, more
than 28,000 metres of drilling has
been completed with encouraging
results. In February 2012, an
NI43-101 compliant resource
estimation was announced (see news
release). The technical report is
filed on SEDAR.com and also
available on ELN's website. An
updated NI43‐101 mineral resource
estimation and metallurgical test
results are slated for completion in
the first quarter of 2013. Results
of these will be incorporated in a
Preliminary Economic Assessment
"PEA" that is slated for completion
in the first quarter of 2013.
ELN and VMC currently own 70% of
the project, of which 35% is held by
each of the two parties. Under a
purchase agreement signed by VMC on
August 28, 2012 with MBM and Murray
Brook Resources Inc. (collectively
the owners), VMC acquired the right
to purchase the additional 30% of
the Murray Brook Project from the
owners. ELN has been provided the
option to purchase an additional 15%
in the project for a combined total
of 50% (35% +15%).
Although the terms of the
Participation Agreement provided for
a three-year period to earn the
initial 50% and two years to earn
the additional 20%, ELN and VMC
completed their earn-in in less than
18 months.
- Bathurst Option Joint Venture
Project (BOJV)
Consists of an initial 4,712
claims in the Tri‐Party Agreement
with Xstrata & VM Canada whereby VM
Canada may incur exploration
expenditures of $10 million over a
period of 5 years to earn a 50%
interest. VM Canada may further
increase its interest to 70% by
spending an additional $10 million
over 2 years.
