TREND MINING ACQUIRES ANDACOLLO GOLD MINE, CHILE

DENVER, Sept. 21, 2005 (PRIMEZONE) -- Trend Mining Company (OTC BB:TRDM.OB -
News) is pleased to announce the final payment of $2.1 million and acquisition
of Compania Minera Dayton ("CMD") and its wholly-owned Andacollo open-pit gold
mine in Chile from Pacific Rim Mining Corp. Up front cash payments have totaled
$3 million since Trend's initial payment was made in June of this year. Total
consideration for the mine is $5.4 million, and further payments of $1 million
and $1.4 million will be made from operating cash flow in September of 2006 and
2007, respectively.

Trend acquired the mine by purchasing the shares of DMC Cayman, Inc., the parent
corporation of CMD. In a simultaneous transaction, Trend transferred 70% of the
shares of DMC Cayman to a group of accredited investors (the "Investors").
Accordingly Trend (now 30%) and Investors (70%) are the new owners of Andacollo,
located 48 kilometers (30 miles) southeast of La Serena in Chile. The mine has
been on standby care and maintenance for five years but will now be readied for
renewed gold production possibly as early as February 2006. The mine is expected
to produce in excess of 250,000 ounces of gold over the next seven years, based
on present proven and probable reserves and production plans. Fully 75% (175,000
oz) of the gold is expected to be produced in the first two years of full
production.

Thomas Loucks, President and CEO of Trend Mining, commented, "Closing this
transaction will enable Trend to become earnings-positive and to fund near term
operations and exploration endeavors from operating cash flow. CMD brings a
talented, Chilean management team that will handle day-to-day mining operations,
while Trend's U.S.-based management will continue to search for larger,
high-upside corporate opportunities. Andacollo's operating cash flows will
strengthen the Company and ease our dependence on equity markets as a source of
operating capital going forward."

Capital to restart the mine will total an estimated $4.4 million and will be
invested over the coming five months. The partners will jointly seek debt
financing but will each provide any equity financing in the proportions of
ownership. Approximately $2.4 million of such capital will be needed to prepare
a new pad for heap leaching, to mobilize a Chilean mining contractor, and to
complete the refurbishment of mothballed equipment. The balance will serve to
provide working capital until the mine attains steady-state cash flow later in
2006. Trend also expects to launch an exploration program at the property in the
near future to identify or prove up new or known gold resources aimed at
prolonging the life of the mine. Additionally, Trend believes there may be
potential for copper mineralization within the existing land package.

Trend Mining Company is a U.S. based minerals company that has 30% ownership of
the Andacollo gold mine in Chile, 100% ownership of the Cree Lake/Diabase
Peninsula uranium project in the Athabasca Basin (subject to Nuinsco Resources
earning 50%), and interests in three North American precious metals properties
with potential for hosting significant amounts of platinum, palladium, gold and
other metals.
