M3 METALS PREPARES FOR TRENCHING AT ITS BLOCK 103 IRON ORE PROJECT

M3 Metals Corp. (TSX -V: MT; FSE: XOVN.F) (“M3 Metals” or the “Company”) is pleased to provide an

update on its upcoming planned trenching program on its 100% owned Block 103 Iron Ore Project in

Newfoundland and Labrador , Canada. The Company has selected 10 priority targets to test for Direct

Shipping Ore (“DSO”) mineralization. Target selection was based on reanalysis of the extensive drilling and

numerous airborne and ground based geophysical surveys including detailed magnetic and gravity

surveys.

The Company is targeting pockets of DSO within and surrounding its primary 7.2 Billion tonne Taconite

(Magnetite Iron) resource (see news release dated Feb 4, 2013). Of immediate interest is a zone of high -

grade haematite mineralization intersected in hole 64 (see below) showing the potential fo r DSO within

and around the resource on the Block 103 property. This mineralization was intersected near surface from

26.82 metres to 32.92 metres and represents one of the initial target areas for the currently planned

trenching program.

DSO highlights from previous drilling

• DDH103-064 including 69.75% Fe2O3 and 16.45%SiO2 over 6.1 metres

DSO is currently being mined by Tata Steel Minerals Canada (“TSMC”) on three sides of the Project and is

being beneficiated at TSMC’s processing facility located 6 kilometres from the Block 103 property . Once

beneficiated, the product is railed to a port in Sept-Îles for shipping to consumers worldwide. TSMC mines

and process high -grade iron ore from multiple isolated hematite deposits occurring over 30 km in the

Menihek region of Labrador and northern Quebec. TSMC is processing iron ore material with greater than

50% total Fe and less than 18% SiO2 as a cut-off for the material at their facility. The Company’s Block 103

Project covers an area of over 72 square kilometres of the Menihek region centrally located within TSMC’s

ongoing operations.

The Company has permits in place for its planned exploration program on its wholly owned Block 103 Iron

Ore Project (the “Project”) in Newfoundland and Labrador , Canada. The current permits include up to

2,000 meters of trenching over 20 separate proposed locations, and up to 13 kilometres of access trai ls

needed to access the target sites. The Company believes there is potential to identify near surface DSO

style mineralization suitable for processing at TSMC adjacent and currently operating beneficiation

facility.

Block 103 is located near well-estab lished infrastructure in the heart of the Labrador Trough,

Newfoundland and Labrador, approximately 30 km northwest from the town of Schefferville, Quebec and

1,200 kilometres by air northeast of Montréal, QC. Previous work by the Company includes geologic al

mapping, geophysical surveys and diamond drilling programs. Total drilling now stands at 115 drill holes

aggregating over 28,000 metres. Two zones of mineralization have been defined on the Property; namely

the Northwest Zone and the Greenbush Zone where the focus of the mineral resource estimate has been

on the Greenbush Zone.
