Lion One Metals Limited (the "Company" or "Lion One") is pleased to announce the following exploration and development update for its Tuvatu Gold Project ("Tuvatu") located near Nadi on the island of Viti Levu, Fiji.

"The Company's geological and metallurgical programs carried out during 2012 overwhelmingly support the continued advancement of Tuvatu," said Mr. Walter H. Berukoff, Chairman and Chief Executive Officer of the Company. "In conjunction with further engineering and environmental studies, our objective for 2013 is to build a robust economic model and complete the permitting process for a high-grade gold mining operation in Fiji."

The Company will continue to test, confirm, and substantially expand historic exploration, 80,000 meters of previous drilling, and metallurgical data from previous feasibility studies. Management believes that the 12,166 hectare Tuvatu property has further resource potential beyond the resource area drilled to date (a surface area measuring 600x200 meters drilled to depths of 300 meters). Tuvatu's geological setting and location in the Navilawa Caldera draws scale comparisons and geological similarities with the Vatukoula gold deposit in the neighboring Tavua Caldera, recognized as one of the giant gold deposits of the SW Pacific.

2012 Drilling Program Overview

The Company commenced its diamond drill program in June 2012, with a total of 3,003 meters of core recovered from 15 diamond drill holes completed to date. Drilling is targeting western extensions of the mineralized structures in the Tuvatu Resource Area, which have now been mapped at surface over a distance of 1km along strike west of the Resource Area, displaying consistent lateral continuity typical of many epithermal lode systems.

The current program has three objectives: (i) infill drilling to increase the confidence level of the existing resource; (ii) step out drilling to expand the resource base; and (iii) exploratory drilling to test additional targets. Initial results confirmed high grades including the following significant intersections:

TUDDH-347: intersected 3.78 m @ 16.15 g/t gold from 122 to 125.77 m (including 0.09 m @ 248 g/t gold)

TUDDH-348: intersected 7.49 m @ 23.03 g/t gold from 155.05 to 162.54 m (including 0.11 m @ 855 g/t gold)

TUDDH-349: intersected 11.9 m @ 11.77 g/t gold from 128.55 to 140 m (including 0.03 m @ 37.7 g/t gold)

The Company expects to increase the resource base through continued drilling and is confident that additional near-surface resources identified to date can also be converted to mineral resources with additional drilling and Management believes the addition of lower-cost oxide resources near surface will significantly enhance the economics of the project in the initial years of development. Drilling is expected to lead to an updated resource estimate in preparation for taking the project into production.

Metallurgical Test Results

Metallurgical studies performed in 2012 confirmed robust gold recoveries from the principal rock types hosting the Tuvatu resource. Recoveries from standard flotation tests ranged up to 94 percent. Because of the coarse nature of some of the mineralization, the study program included gravity tests to determine the amount of recoverable free gold. In addition two mill flow sheets for processing the gravity tailing were also completed. Significant conclusions of the study include:

--  Gold is free-milling by conventional gravity and flotation processing at
    reasonable grind sizes
--  Gravity recoveries averaged over 40%, and combined gravity and flotation
    ranged up to 94%
--  Mineralization is clean with respect to deleterious elements such as
    arsenic, selenium, and uranium
--  Testing indicates conventional crushing, two-stage ball milling and
    three points of gravity concentration in the crushing and milling
    circuits, followed by conventional flotation and CIL leaching or direct
    sale of concentrates will produce optimum recoveries.

Environmental Impact Assessment

An independent consultant approved by Fiji's Mineral Resources Department (MRD) is currently conducting an Environmental Impact Assessment (EIA) on Tuvatu. The findings of the EIA will be reported to the MRD and will be included in the filing of the mining license application that the company expects to file with the MRD in Q2 2013.

Fiji Survives Level 4 Cyclone Evan

The government of Fiji declared a State of Natural Disaster for parts of the island nation in the wake of Cyclone Evan, the largest and strongest cyclone to hit the country in over 20 years. The Company is pleased to report that all of its employees and their families are safe and that the Company's operations have not been jeopardized. Apart from damage to the Company's workshop in its Nadi head office compound and to the Tuvatu site mess hall the head office and Tuvatu site camp facilities are intact.

Results of AGM

The Company's Audited Consolidated Financial Statements for the year ended June 30, 2012 were received and considered at its Annual and Special Meeting held on December 12, 2012. Shareholders of the Company also considered and approved resolutions in favor of the:

--  Re-election of the Directors of the Company: Walter H. Berukoff, George
    S. Young, David Duval, Richard Meli, Stephen Mann, and Hamish Greig
--  Re-appointment of Ernst & Young, chartered Accountants, as Auditor of
    the Company, and
--  Approval and ratifications of the Company's "Rolling 10%" Stock Option
    Plan

Technical Information and Qualified Persons

The assay analyses performed during Lion One's drilling programs are subject to a formal quality assurance and quality control (QA/QC) program. Diamond drill core was logged and sampled on site at Tuvatu by Company staff with samples delivered by the Company to the facilities of Australian Laboratory Services (ALS) Pty. Ltd., an independent accredited analytical laboratory. Samples are first prepared and crushed at the ALS facility in Suva, Fiji, before being shipped to Brisbane, Australia for assay analysis. Samples are subjected to fire assay with atomic absorption finish for gold and 33 elements, four acids, and Inductively Coupled Plasma Spectrometry (ICP-AES). Standard reference materials, blanks, and field duplicates samples are inserted prior to shipment from site to monitor the quality control of the data. Samples with higher grade gold (greater than 3 grams per tonne) are reassayed using a gravimetric and/or pulps and metallic procedure.

About Lion One Metals Limited

Lion One Metals is focused on the exploration and development of prospective multi-million oz. gold deposits in the Fijian Islands. The Company's flagship Tuvatu Gold Project is situated in the Sabeto Valley, along Fiji's corridor of mineralized volcanic centers, approximately 50 km southeast of the 11 million ounce Vatukoula gold deposit. The Fijian Islands exhibit similar "island arc" geology that gives rise to many of the SW Pacific's major gold deposits such as Vatukoula, Ok Tedi, Porgera, and Lihir.
