Statement re Royalty Acquisition

8 October 2013

BlackRock World Mining Trust plc (the "Company") - Royalty Acquisition

The Board of BlackRock World Mining Trust plc announces that the Company has
reached a non-binding agreement on key commercial terms with regard to a US$12m
net smelter return royalty investment (the "Royalty") with Avanco Resources
Limited in respect of its whole licensed area in Carajas, Brazil comprising
Antas North deposit ("Antas North" or "Stage 1"), Pedra Branca deposit ("Pedra
Branca" or "Stage 2"), and other discoveries within Avanco's current licensed
portfolio. The Royalty would offer the Company a 25% royalty payment on gold
production and 2% on production of other metals including copper produced from
the whole licensed area of Stage 1 and Stage 2. A flat 2% royalty will be
applied to all other projects from the rest of Avanco's licensed area.

The Company and Avanco Resources Limited will shortly begin to work on the
heads of terms for the Royalty investment, followed by negotiation and signing
of the definitive legal documentation. Avanco Resources Limited will grant
BlackRock a period of exclusivity to conduct due diligence to its satisfaction
and agree the tax and legal structure of the investment. Signing of the
definitive legal documentation in relation to the Royalty investment is
expected to complete by year end and completion of the Royalty investment will
be subject, inter alia, to the obtainment of a mining license and publication
of a JORC (Australasian Joint Ore Reserves Committee) compliant reserves
statement in relation to Antas North by Avanco Resources Limited or its
subsidiary. Neither Antas North nor Pedra Branca is yet a producing asset, but
it is anticipated that construction of Antas North will commence during 2014.

Whilst a relatively small investment for the Company and early stage in terms
of the profile of the Avanco mine development in Brazil, the Board believes
that this investment offers an attractive addition to the investment portfolio
as it expands by size and diversifies by assets the Company's existing royalty
holdings. This transaction would bring total unquoted investments within the
Company's portfolio to a pro forma aggregate percentage of 9.15% of Gross
Assets (as at 4th October 2013).

The Board and Manager continue to view royalties as an attractive method of
accessing mining revenues and achieving direct long term commodity price
exposure whilst stripping out cost inflation.

Further to the approval by shareholders of the Company's amended investment
policy on 21 August 2013, the Board expects that the Company will continue to
deploy capital, up to the unquoted holding limit of 20% of gross assets, in
royalty related investments as appropriate assets become available at the right
price, and will communicate further acquisitions to shareholders in due course.
