NON RENOUNCEABLE ENTITLEMENTS ISSUE

Black Ridge Mining NL ( Black Ridge or Company ) confirms its intention to undertake a non-renounceable entitlements issue on the basis of one (1) new share for every four (4) shares on issue at 1 cent per share to raise approximately $1.5 million (before costs).

It is proposed that one (1) free attaching option will be issued for each share issued. The free attaching options will be exercisable at 1.5 cents each and expire approximately 18 months from date of issue. It will be a term of these free attaching options that in the event they are exercised within the first four (4) months from grant ( Initial Period ), a new option will be issued for no further consideration. The new options will be exercisable at 1.8 cents each and expire on or about 18 months from expiry of the Initial Period.

Further information regarding the entitlements issue (including the terms of the securities offered) will be set out in a prospectus to be lodged with the Australian Securities and Investments Commission in the near future.

Funds raised from the offer will be allocated to the Company’s existing exploration programme at Unaly Hill, Western Australia and to provide additional working capital to fund costs associated with the Company’s continued investigation of new project opportunities both in Australia and overseas.

For further information, please contact David Semmens on (08) 9322 7822.
