Tri-Valley Reveals Strong Investor Interest for New Equity and Project Investments

BAKERSFIELD, Calif., Sep 29, 2009 (BUSINESS WIRE) --
TIV | Quote | Chart | News | PowerRating -- Tri-Valley (NYSE AMEX:TIV) is currently reviewing proposals from several
private equity groups who have expressed interest in making significant
equity investments in the Company to advance its Alaskan gold properties
and its heavy oil project at Oxnard, California. The Company is also in
discussions with other investor groups who wish to invest directly in
the projects themselves. Management is working closely with the Board of
Directors in evaluating these proposals to maximize value for the
Company's shareholders.

Additionally, Tri-Valley is completing final well-work to improve steam
injection on the last two of its seven horizontal wells on the Hunsucker
Lease at Oxnard, and expects to have higher oil production from all
seven wells in October. The Company expects to receive a new reserves
evaluation report for its Oxnard heavy oil project in early October that
is being prepared by a well-respected Canadian petroleum consulting firm
with extensive experience in thermal oil recovery systems including
Steam Assisted Gravity Drainage which is being widely deployed in the
Canadian Athabasca oil sands region and being planned for deployment at
Oxnard.

Tri-Valley will prepare a plan for submission to NYSE Amex by October
23, 2009 that will outline initiatives that will increase its
shareholder equity in order to mitigate a compliance issue with respect
to its reported shareholders' equity as of June 30, 2009. On September
23, 2009, NYSE Amex LLC notified Tri-Valley Corporation by letter that
the Company is not currently in compliance with a certain standard for
continued listing on the exchange as required under the NYSE Amex
Company Guide. Specifically, Section 1003 (a)(iii) of the Company Guide
requires a company to maintain a minimum of $6 million in stockholders'
equity if that company has sustained losses from continuing operations
and/or net losses in its five most recent fiscal years. Tri-Valley's
Form 10-Q for the quarter ended June 30, 2009, reported stockholders'
equity at June 30, 2009, of $5,169,833. NYSE Amex's notification had
been expected by the Company.

Under NYSE Amex rules, Tri-Valley has until October 23, 2009, to submit
a plan to regain compliance with Section 1003(a)(iii) of the Company
Guide. Tri-Valley is preparing to submit its plan to regain compliance
in accordance with NYSE Amex rules. If the company does not submit a
plan or if the plan is not accepted by the exchange, the company will be
subject to delisting procedures as set forth in Section 1010 and part 12
of the Company Guide.

With the financing initiatives underway that will increase stockholders'
equity above the $6 million minimum as required by the NYSE Amex rules,
the Company believes that its plan that will be submitted by October 23,
2009 will clearly show its ability to increase equity beyond the
exchange's minimum threshold to regain compliance and continue its NYSE
Amex listing.

Tri-Valley has been in business as a successful operating company
since 1963, and has been a full reporting 12 (g) publicly traded
Delaware Corporation since 1972. Tri-Valley Corporation stock is
publicly traded on the New York Stock Exchange AMEX under the symbol
