June 5, 2013. Vancouver, BC; El Nino Ventures Inc. ("ELN"and the Company") (TSX.V: ELN; OTCQX: ELNOF Frankfurt: E7Q) is pleased to announce the results of an NI 43-101 Preliminary Economic Assessment ("PEA") for the Murray Brook polymetallic massive sulfide deposit, New Brunswick (the "Project"). The results of the PEA demonstrate the potential technical and economic viability of establishing a new mine and mill complex on the Murray Brook property. The projected cash flows indicate an after-tax NPV at a 5% discount rate of $96.4 million, an IRR of 11.4%, and a payback period of 5.4 years (see table 1). An NI 43-101 Technical Report will be filed on SEDAR within 45 days of the date of this press release.

Harry Barr, ELN's Chairman & CEO commented, "The results of the PEA clearly indicate that there is an indicative basis for a mining project at Murray Brook. There is excellent potential to further enhance the projected economics of the project, through continued refinements in metal recoveries as well as the potential to augment existing resources by achieving an exploration success on the adjacent Camel Back claims. With forecasts of increased metal demand and dwindling supply, the positive PEA results for the Murray Brook project provide ELN shareholders with the potential to benefit from the predicted upward trend in zinc prices over the next few years".

Unless otherwise noted, all amounts in this press release are expressed in Canadian currency. The PEA is prepared for 100% ownership of the project revenues and expenditures. As noted below, ELN holds a 35% interest in the project. The PEA includes Inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.

The PEA was prepared by P&E Mining Consultants Inc. and the full results of the study will be disclosed in a NI 43-101 Technical Report within 45 days of the date of this press release. The PEA was prepared under the supervision of Eugene Puritch, P. Eng. of P&E Mining Consultants Inc. Mr. Puritch is an independent QP in accordance with NI 43-101 and has reviewed and approved the technical information in this release.

The main conclusions from the PEA follow below.

Mining and Mineral Processing

Life of Mine production on a diluted and extracted basis for the Murray Brook potentially economic portion of the resource estimate is planned to be as follows:

Table 2 - Murray Brook Potentially Economic Portion of the Resource Estimate

(1) Potentially economic portion of the mineral resource estimate which are not mineral reserves do not have demonstrated economic viability. This estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

(2) The quantity and grade of reported potentially economic Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define them as an Indicated or Measured potentially mineable mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured potentially economic mineral resource category.

(3) The potentially economic portion of the mineral resource in this press release was 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 Standing Committee on Reserve Definitions and adopted by CIM Council.

The PEA assumes the start of the open pit mining operations at an average annual process plant production rate of 2,000,000 tonnes per annum over a mine life of approximately 9.5 years. The envisaged mining operation is a conventional open pit. Mining operations will reach a sustained total annual material movement of 11.6 million tonnes using 11.5 m3 diesel hydraulic excavators, 90 tonne haulage trucks, and track mounted diesel powered drill rigs with up to 100 mm diameter blastholes drilled on 6 metre high benches.

The mined material will be processed at a new 6,000 tonnes per day flotation plant located on the Project site. Three concentrates will be produced: 1) copper-silver; 2) lead-silver; and 3) zinc-silver. It is anticipated that the concentrates could be processed at the nearby Belledune Smelter or other suitable facilities.

Site Infrastructure

The Project will benefit from infrastructure, services and skilled labour available in the Bathurst Mining Camp. The Murray Brook Project site is located 60 km west of the city of Bathurst and is accessible year-round from paved Provincial Highway 180 and a 6.5 km gravel access road. Project site infrastructure is anticipated to include:

• Plant site and haul roads;
• Administration buildings and assay lab;
• Mine maintenance garage, warehouse and fuel storage facilities;
• Fresh water supply and sewage treatment; and
• Lined tailings storage area

The proposed Murray Brook Project mill and mine site is ideally located on the access road to the open pit area. The proposed processing plant site is located on a ridge overlooking a valley about 100 metres below. Several lateral ridges form natural containment dykes for at least two sides of a tailings management facility. Power to the site will be supplied by a 12 km long transmission line connecting to the Caribou Mine site and provincial grid.

The labour force for the construction and operation of this project is anticipated to be drawn from the Bathurst area. The labour pool in this area is highly skilled and experienced in construction projects and mining operations.

Financial Assumptions and Results

Total operating costs during the Life of Mine is illustrated in Table 3:

Table 3-Projection of total operating costs during the Life of Mine, Murray Brook Project

Capital costs are categorized as Initial Project Capital and Sustaining Capital. Initial Project Capital consists primarily of mining equipment, process plant and ancillary plant construction, initial tailing storage, facility construction, an allowance for water treatment, and local infrastructure. Sustaining capital consists of further additions to mining equipment during production and environmental and closure costs.

Metal prices used in the PEA are based on the April 30, 2013 three year trailing prices which are listed in Table 5 below.

Project and Exploration Upside

Further technical studies on the Murray Brook Project will focus on additional metallurgical studies designed to evaluate potential techniques of improving metal recoveries. The first step is a small pilot plant project proposal to test three to five tonnes of drill core material.

The largest impact on the potential value of the Murray Brook Project is likely to be achieved by increasing the mineral resource base available for mining, thereby increasing the mine life and (or) annual mill throughput. Excellent potential exists for additional discoveries along and adjacent to the favourable geological horizon which extends from the former Restigouche Mine to the west of the Murray Brook deposit deposit to Trevali's productive stratigraphy could significantly increase the scale of the Murray Brook Project prior to development. A 2,000 metre exploration program is proposed to drill test five priority geophysical and geochemical anomalies this summer.
