VANCOUVER, Feb. 28, 2012 /CNW/ - El Niño Ventures Inc. ("ELN" and the "Company") (TSXV: ELN) (OTCQX: ELNOF) (Frankfurt: E7Q) is pleased to announce receipt of an initial NI 43-101 Mineral Resource Estimate for the Murray Brook polymetallic massive sulfide deposit in the Bathurst Mining camp, New Brunswick, Canada. The resource estimate was prepared by P&E Mining Consultants Inc. and G.A.Harron and Associates Inc. It is based on 60 vertical drill holes, totalling 10,327.5 metres that were drilled during the 2011 drilling program. A technical report will be posted on SEDAR within 45 days of this news release.

2012 Mineral Resource Estimate

The resource estimate, which includes explanatory footnotes, is tabulated below in Table 1. The resource estimate is based on various assumptions regarding mining methods, processing and metal recoveries, payable metal NSR credits and metal prices. This estimate makes no provision for capital costs to mine the deposit, nor mill the material mined, as resources are not reserves and the reader should not presume economic viability.

Table-1 Murray Brook Mineral Resource Estimate Summary

Mineral resources which are not mineral reserves do not have demonstrated economic viability.
The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

(1) The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.
(2) The mineral resources in this news release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standard Committee on Reserve Definitions and adopted by CIM Council
(3) The Dec 31, 2011 two year trailing average US metal prices used in this estimate were $3.71/lb Cu, $1.03/lb Pb, $0.98/lb Zn, $1,397/oz Au, $27.63/oz Ag. The C$/US$ Exchange rate was 0.99.
(4) Overall payable metal in the NSR calculation were 81% Cu, 72% Pb, 64% Zn, 71% Au and 56% Ag.
(5) Mineral resources were determined within a Whittle pit shell with 45 degree slopes utilizing mining costs of C$2.50/tonne for mineralized material and waste rock, and C$1.75/tonne for overburden.
(6) Costs used to determine the C$20/tonne NSR resource cut-off value were processing at C$15/tonne and G&A C$5/tonne.
(7) The Murray Brook Mineral Resource Estimate was undertaken by Eugene Puritch, P.Eng. of P&E Mining Consultants Inc.

As a further approximation the total metal content can be recalculated as a zinc equivalent (ZnEq), which would equate to 8.17% ZnEq for the Measured plus Indicated resources and 8.47% ZnEq for the Inferred resources, based on calculating the total NSR value of the constituent metals in the table above plus the smelting and shipping charges all divided by $14.05, which is the recovered value of 1% Zn.

This initial NI43-101 compliant resource estimate, as provided above in Table 1 including explanatory footnotes, supercedes previous historic estimates which understated metal grades due to widely spaced drilling and incomplete metal assays. The Murray Brook Deposit remains open to the northwest and there is good potential to increase both tonnes and grade with additional exploration and infill drilling, respectively.

Contained metal contents as calculated by El Niño Ventures Inc. are summarized below in Table 2.

2012 Exploration Plans

A $3 million budget has been proposed for the 2012-2013 exploration program that includes $2.5 million budgeted for drilling measured resources at the Murray Brook deposit and $500,000 exploration program on Murray Brook and Camel Back exploration claims defined by the option agreement with Murray Brook Minerals (Figure 1). The objective of the exploration plan is to search for large VMS deposits that might occur at depths of up to 150 metres below surface. The area to be explored is located between the Murray Brook massive sulfide deposit, which is the 5th largest in the Bathurst Mining Camp (BMC), and the nearby Caribou deposit, which with total historic resources estimated to be 65 million tonnes, is the camp's second largest massive sulfide deposit.

The Exploration Agreement

Votorantim is the Operator of the Murray Brook Project. In January 2011, ELN announced that it provided notice to Votorantim Metals Canada Inc. (Votorantim) to enter into a Participation Agreement on the Murray Brook polymetallic massive sulfide deposit situated in the Bathurst Mining Camp in New Brunswick, Canada. (See news release dated January 20, 2011).

Under Votorantimʹs Option and Joint Venture Agreement with Murray Brook Minerals and Murray Brook Resources, both privately held companies, Votorantim can earn a 50% interest in the properties by funding $2,250,000 in exploration expenditures and making payments totalling $300,000 over a three year period that commenced November 1, 2010. Votorantim can earn an additional 20% interest in the properties by funding an additional $2,250,000 in exploration expenditures over an additional two year period. ELN has elected to enter into a participation agreement wherein it can earn 50% of Votorantim's interest by paying 50% of the costs incurred by Votorantim in the Option and Joint Venture Agreement.

The Murray Brook Deposit

The Murray Brook deposit is a polymetallic, volcanic hosted massive‐sulfide deposit in the Bathurst Mining Camp, New Brunswick. The property is located approximately 60 km west of the town of Bathurst. A gravel road links the property to a paved highway. An electricity grid is nearby, as are communities with goods, services and skilled labor. The Gossan Zone overlying the massive sulfide deposit was mined for gold and silver during the open‐pit mining operations carried out by Novagold Resources Inc. during the early 1990s. The hanging wall is moderately chloritic and is locally intensely deformed. The foot wall consists of fine grained, felsic tuff and tuffaceous sediments with moderate to strong chlorite and sericite alteration. Sulfides are mainly fine grained, massive, weakly laminated pyrite with disseminated and banded sphalerite, chalcopyrite and galena.

The first phase of the 2011 drill program was completed in spring/summer 2011 and significant intersections of zinc, copper, lead, gold and silver were reported. The second phase of the drilling program was initiated in September 2011 and the results announced (please see news releases dated August 30, 2011, November 28, 2011, January 16th and January 23, 2012).
