ASX Release

27 May 2015

RIGHTS ISSUE

1 FOR 2 RIGHTS ISSUE AT $0.02 PER SHARE TO RAISE $2.4m

OVERVIEW

The Board of Dart Mining NL (“Dart” or the “Company”) has today announced that the Company has launched an accelerated non-renounceable 1 for 2 rights issue (“Entitlement Offer”). The capital raising will involve the issue of up to approximately 121,628,991 ordinary shares to raise $2,432,580 (before costs of the issue). The issue will close on Friday 26 June 2015*

The new shares under the rights issue are to be issued at a price of 2 cents per share. While it is not unusual for a volume weighted average price (VWAP) over a variety of periods to be applied to rights issues with the result proposed as a discount to market close, trade in Dart shares DTM has been relative low so as to make such a proposal in the Board’s view unrepresentative of value.

Eligible shareholders will be sent a copy of the Entitlement Offer and Application Form on 5 June 2015. An electronic version of the Entitlement Offer Letter will be available on the Dart website. Eligible shareholders will be sent their personalised Entitlement and Acceptance Form on 5 June 2015, or can access their personalised Entitlement and Acceptance Form from https://www.linkmarketservices.com.au/corporate/home by following the security access requirements.

COMMENTS FROM DART’S CHAIRMAN

Bruce Paterson, Chairman of Dart Mining said, in relation to the rights issue “ Release of the Project Definition Study (PDS) results for the Unicorn Molybdenum, Copper, Silver, Zinc Project is a massive milestone offering a clear vision for the Unicorn Project delivering significant benefits to Dart and its shareholders and exceeding expectations.

Having reached the critical milestone of Project Definition of the Unicorn Project the Company is faced with a compelling need not only to maintain secure tenure over its prime asset but also to continue methodical progress and refinements of its time-critical elements. This process aims to position Dart and its shareholders to ensure that as the commodity

cycle turns positive, Dart and the Unicorn Project are ready as possible as to take full advantage of the upturn.

Now is the right time for all shareholders to have the opportunity to be a further part of this exciting turnaround to further and support the growth of their investment in the Company. Following conclusion of the transaction, Dart will be well placed to address its organic growth pipeline and to deliver additional projects which complement Dart’s existing portfolio.”

Mr Paterson added, “The closing date for the rights issue is after the scheduled General Meeting on 18 June 2015 pursuant to the Section 249D notice. This ensures that voting is not impacted by the Rights Issue and allows shareholders who support the current Board’s progress on Unicorn to further participate in its exciting future”.

Shareholders are asked to read the concurrent Unicorn Project Definition Study announcement which has been lodged with the ASX and sets out in some considerable detail the forward plans for Dart and Unicorn under this enhanced definition and business case.
