The unaudited net asset values for BlackRock World Mining Trust plc at close of
business on 22 December 2014 were:

332.66p Capital only (undiluted)
347.04p including current year income (undiluted)

Notes:

1. Banro Corporation announced on 4th November 2014 that they had secured
US$41m of financing through the forward sale of 40,500 ounces to Gold Holding
Ltd. Subsequent uncertainty over the timing of the closure of this transaction,
coupled with a balance sheet update provided in their Q3 results released on 11
November, meant as at the end November 2014 the Trust held the Banro
gold-linked preference shares at a 30% discount to the implied gold price used
in the valuation of these preference shares.

Post month end, the Board has noted the lack of recent trading activity and
ongoing financing uncertainty in Banro Corp 10% Note (March 2017), in which the
Company is invested. The Board has concluded, based on a recommendation from
BlackRock's pricing committee, that it is appropriate to value the Company's
investment in the Banro Corp 10% Note at a 25% discount to its last traded
price (on 21 November 2014). This gives a valuation for the Company's
investment in the Banro Corp 10% Note of £6.45m (previous valuation £9.09m), an
impact to the NAV of approximately 1.49 pence.

As at 10 December 2014, the total exposure to Banro Corporation sits at 2.88%
of the NAV, of which the corporate bond represents 1.03% and the gold-linked
preference share represents 1.85%.

2. Revenue items included in net asset value, with dividends payable deducted
on the ex-dividend date.

3. The undiluted net asset value per share has been calculated on 177,287,242
ordinary shares excluding 15,724,600 held in treasury.
