TANGO ENTERS DIAMOND MINING SECTOR IN ANGOLA

VANCOUVER, BRITISH COLUMBIA — 11 September 2017 – Tango Mining Limited (“Tango” or the “Company”)

(TSXV:TGV) is pleased to announce that it has signed a three year renewable Services Agreement for Mining and

Marketing of Diamonds with Txapemba Canguba R.L (“Txapemba”) which is a Cooperativa Exploração Semi-Industrial de

Diamantes located in the Municipality of Cambulo, Province of Lunda Norte, Republic of Angola. Txapemba was granted

an 84 square kilometer (“km”) concession for the semi-industrial exploitation of diamonds within the Luembe River basin

in an area that was a past alluvial diamond producer and well known for both alluvial and kimberlite diamonds (the

“Property”).

Tango will be responsible for capital expenditures associated with alluvial mine design and equipment acquisition and will

be the sole operator. As remuneration, Tango will receive 60% of the proceeds from the sale of produced stones. All of

Tango’s operational costs are deductible.

The Property is located immediately near the community of N ’zagi (Andrada) and 95 k m south east of Dundo, the

provincial capital of Lunda Norte, which has a recently reopened airport with direct service to Luanda. Angola, which ranks

as the world’s fifth biggest producer of diamonds by value has been actively encouraging foreign investment in its

diamond sector under a new Mining Code introduced in 2011, which no longer includes the requirement for Angola to

hold a majority interest in diamond mining projects.

Angola’s potential for world class diamond discoveries is recognised by global diamond mining leaders Alrosa and De

Beers. Alrosa is the operator of the world’s fourth biggest diamond mine Catoca, which is located 220 km southwest of the

Property and within the same geological setting (Lucapa Graben). Angola is an official signatory of the Kimberley Process

Certification Scheme and occupied the position of Chair of the Kimberley Process in 2015.

Development Plan

Tango will, over the coming months, complete a full geological assessment of the Property and plans to commence alluvial

diamond production as soon as practical.

Txapemba Property

The Property is located within the Luembe Ri ver drainage in north east Angola and constitutes the bulk of the alluvial

diamonds extracted until now in Angola and represent a large fraction of the still existing diamond resources. The

Chiumbe, Luembe, Luachimo and Chicapa rivers’ basins deposits are the most important, only surpassed by Cuango

River’s. Secondary (or alluvial ) diamond deposits were formed in several cycles, starting immediately after kimberlite

emplacement (in Cretaceous times, generally speaking). The first secondary deposits correspond to the basal

conglomerates of what is known as the Ca londa Formation. The erosion of these conglomerates released diamonds that

would be concentrated in more recent deposits.

The Property is located within a few km from the Chimbongo and Chitololo alluvial diamonds mines.

The area has a high potential for a primary source, as the Malúdi diamond population has different properties than those

of the general diamond population in the area.

and demand for, deliveries of and the level and volatility of prices of rough diam onds, risks that the actual revenues will be

less than projected; risks that the target production for the existing mining contracts will be less than projected or

expected; risks that production will not commence as projected due to delay or inability to receive governmental approval
