North Vancouver, B.C., September 15, 2017. Lion One Metals Limited (TSX-V: LIO) (ASX: LLO) (OTCQX: LOMLF) (FSX: LY1) (the 'Company') is pleased to announce further drill results from the current diamond drilling program at its 100% owned and fully permitted high grade underground Tuvatu Gold Project located near Nadi on the island of Viti Levu in the Republic of Fiji. This phase of drilling targeted both the new zone of shallow mineralization reported on in the previous news release dated 22 August 2017 (Drilling Identifies New Zone of High-Grade Mineralization at Tuvatu Gold Project in Fiji), as well as infill and follow up drilling of the existing resource area from both the surface and underground.

Diamond drilling
Results have been received from a number of additional diamond drill holes completed at Tuvatu gold project in Fiji. The focus of the drilling of this program of work was threefold; firstly to extend the new zone of mineralization reported in the recent news release (22 August 2017), secondly to infill inferred zones of mineralization targeted for early development, and thirdly to undertake a first pass review of the target horizons striking south of the known mineralization. (Figure 1)

Surface diamond drill holes TUDDH 452 - 462 are further holes targeting the new zone of mineralization reported on in the last news release dated 22 August 2017. (Figure 2, 3)

This new mineralized zone is adjacent, but separate, to mineralization previously outlined in the Tuvatu resource, and to the north of any previously defined planned ore blocks for mining, as can be seen in Figure 2. The grades intersected are significantly higher than other drill results in this immediate area and are located in the near-surface providing the possibility for early development. The current drill program is focused to the north of the east-west striking Core Shed Fault, a structure which bisects the northern end of the Tuvatu resource. Previous drilling to the north of the Core Shed Fault has identified limited and generally lower grade mineralization. The recent drilling has helped tie together these previous results and extend the known mineralization further north, and with higher-grade results than previous work had indicated. Although drilling on this target has focused on those areas north of the Core Shed Fault, this zone of mineralization is open to the northwest, southeast and at depth. Drilling has continued in an effort to determine the extent of mineralization in both directions along strike, and down-dip. All intersections to date are shallow, and all indications are that the mineralization will continue down dip and along strike.

The new drilling is characterized by fine quartz veins, pyrite rich, vuggy, bleached monzonite, with zones of intense, very coarse grained biotite and -potassium feldspar alteration. The zone is characterized by intense fractures, breccia and minor faults.

Underground collared diamond drill holes TUG 114 - 129 (Figure 4), in addition to surface diamond drill holes TUDDH 429 - 431, TUDDH 434 - 441, and 443 - 447, (Figure 5) are infill holes targeting inferred areas of the existing resource at Tuvatu. Additionally, surface diamond drill holes TUDDH 432 - 433, and TUDDH 443 - 447 (Figure 6) were completed further to the south of the existing resource as a first pass examination of the extent of the mineralized structures in that area.

Results from a number of diamond drill holes which have recently been received (see Table 1), are reported in this release. The detailed logistics of each hole are included in Table 2. The drill program is continuing with results from a number of additional holes still outstanding. The location of these drill holes is outlined in Figures 1-6.

Notes: * Denotes diamond drill holes previously reported in News Releases dated 22 August 2017
For surface diamond drill holes, 10 to 20 meters of the poorly consolidated surface material was drilled using PQ3 (83.0mm core diameter) diamond core with remainder of the hole drilled with HQ3 (61.1mm core diameter) diamond core. For underground diamond drill holes, the entire hole was drilled in NQ3 core (47.6mm)
Downhole surveys are carried out using a Ranger Explorer Mark 2 electronic multi-shot camera.
Downhole surveys are taken at least once every 30 m.

Geological Mapping
Geological mapping along the HT Mineralised Structure along strike to both the north-west and south-east of this current new zone of drilling has highlighted the potential significant extent of the target zone. The prospective horizon has been mapped for over 1 km to the north-west, and in excess of 2 km south-east of the Core Shed Fault. The figure (Figure 2) below demonstrates the area which has been drilled to date, and the extensions to the area which have now been mapped, and highlights the very significant exploration upside this new zone has bought to the already high grade Tuvatu project area.

Geological mapping and trenching will continue along strike in both directions to more accurately determine the location and gold tenor of this structure in this rugged terrain.

Extensional Exploration at Tuvatu
The Tuvatu Gold Project consists of multiple high-grade structures drilled over a strike-length of approximately 900 meters. Several of the mineralized zones are open along-strike and down-dip and, as noted in this release, there are potential new target areas in the immediate vicinity of the known mineral resource. The first target area for these extensions has highlighted the mineralization identified in Figure 3. The second extensional zone targeted includes the confluence of structures to the south of the existing resource with the holes highlighted in Figure 6. Tuvatu sits within an extensive mineralized district with gold occurrences and geochemistry anomalies extending over an area 6 kilometers by 3 kilometers with several district prospects yet to be adequately tested. The Company is developing an exploration strategy that focuses on new mineralization within the current mineralized envelope, immediate extensional targets and other targets in the district. The aim is to expand the resource base to continue to support long-term sustainable mining operations at Tuvatu.

About Tuvatu | Lion One | Fiji Gold
Lion One is aggressively advancing its 100% owned Tuvatu Gold Project as a world class discovery and near-term production opportunity in the southwest Pacific Ring of Fire. Tuvatu is modeled for exploration after regional giants in the low sulphidation family of high grade epithermal gold deposits such as Porgera and Lihir in PNG, and Vatukoula in Fiji. These spectacular discoveries have produced over 35 million ounces of gold in similar alkaline volcanic settings. Tuvatu has been fully permitted by the Government of Fiji for operations startup and has a dual-track strategy of production development and resource expansion inside its 385 hectare mining lease.

Tuvatu is located 17 km from the international airport in Nadi, on the west coast of Viti Levu in the Republic of Fiji. Lion One's CEO Walter Berukoff is leading an experienced team of mine builders, and has owned or operated over 20 mines in 7 countries. As the founder and former CEO of Miramar Mines, Northern Orion, and La Mancha Resources, Walter is credited with building over $3 billion of value for shareholders.

Tuvatu was advanced by previous owners through underground exploration and development from 1997 through to the completion of a feasibility study in 2000. Acquired by Lion One in 2011, the project has over 110,000 meters of drilling completed to date in addition to 1,430 meters of underground development.

In January 2016 the Hon. Prime Minister of Fiji, Mr. V. Bainimarama, formally presented the previously granted Tuvatu Mining Lease to Lion One. This concluded the permitting process for the development of an underground gold mine and processing plant at Tuvatu, demonstrating strong government support for Fiji's 85 year-old gold mining industry.

As per its independent June 1, 2015 NI 43-101 PEA Technical Report on the Tuvatu Gold Project, the Company envisages a low cost underground gold mining operation producing 352,931 ounces of gold at head grades of 11.30 g/t Au over an initial 7 year mine life. This includes production of 262,000 ounces at 15.30 g/t through to the end of year three. Estimated cash cost is US$567 per ounce with all-in sustaining cost of US$779 per ounce. Total capex of US$48.6 million includes a contingency of US$6.1 million with an 18 month preproduction schedule and 18 month payback on capital. At a US$1,200 gold price, the project generates net cash flow of US$112.66 million and an IRR of 52% (after tax). The Company is not basing its production decision on a feasibility study of mineral reserves demonstrating economic and technical viability; as a result there is increased uncertainty and economic and technical risks associated with its production decision.

Mine engineering and underground development is progressing alongside final detailed engineering for the Tuvatu processing plant and site infrastructure. The Company has now dewatered the existing Tuvatu exploration decline to 560 meters from the portal down the decline. The decline was completed in the year 2000 by Emperor Gold Mines, comprising 1,430 meters of underground development including drives, cross cuts and raises. In conjunction with the dewatering, ventilation fans and lighting have been installed and are running 24 hours per day. The rehabilitation of the decline is ongoing as dewatering progresses, but in general the stability and ground conditions have been shown to be very good. The areas of rehabilitation and regularly reviewed and approved by Mine Inspectors from Fiji's Mineral Resource Department.

Stephen Mann, Managing Director of Lion One Metals and member of The Australasian Institute of Mining and Metallurgy, is the Qualified Person ('QP') responsible for the Tuvatu Mine exploration and delineation programs. Mr. Mann has prepared and approved the scientific and technical disclosure in the news release.
