MMP.UN Precious Metals and Mining Trust

Precious Metals and Mining Trust (the "Trust") (TSX: MMP.UN) wishes to provide unitholders and warrant holders with an update on the Trust's warrant offering.

On March 16, 2010, the Trust announced that it would issue warrants (the "Warrants") to subscribe for Trust units (the "Warrant Offering") to its unitholders of record at the close of business (Toronto time) on March 30, 2010 (the "Record Date").

Unitholders received one Warrant for each Trust unit held on the Record Date.

The Warrants can be exercised up until the expiration date of July 23, 2010 at 4:00 p.m. (Toronto time) (the "Warrant Expiry Time"). Warrant holders should contact their broker or investment advisor in advance of the Warrant Expiry Time as each broker or investment advisor may require additional lead time to process a request.

Warrants and subscription price

One Warrant entitles the holder to purchase one Trust unit at a price of $7.42 per unit (the "Exercise Price") before the Warrant Expiry Time. On June 24, 2010, the Trust's net asset value per unit at the close of business was $9.01 and the Trust's fully diluted net asset value was $8.55. On June 28, 2010, the Trust's closing market price was $8.20.

Discount to NAV and market price

The subscription price of $7.42 represents a discount of 13.2% to the fully diluted net asset value per Trust unit on June 24, 2010 and a discount of 9.5% to the market price per Trust unit on June 28, 2010.

Proceeds and expenses of the Offering

If all of the Warrants are exercised, the Trust will issue 9,717,733 Trust units for net proceeds of approximately $70.26 million after deducting the payment of the expenses of the Warrant Offering and the Warrant exercise fee by the Trust.

Additional subscription privilege

Each Warrant holder who has subscribed for all of the Trust units to which such holder is entitled may subscribe pro rata for additional Trust units, if available, that were not subscribed for initially, at a price equal to the Exercise Price.

Listing and trading

The Warrants began trading on the Toronto Stock Exchange (the "TSX") on March 26, 2010 under the symbol MMP.WT. On June 28, 2010, the Warrants' closing market price per warrant was $0.84.
