Grant Thornton LLP, Chartered Accountants, the prior auditors, resigned August 2, 2006. The Company proposes to have its shareholders ratify and confirm the appointment of PricewaterhouseCoopers LLP, Chartered Accountants, as its auditors at the next annual meeting of the Company.

The Notice included the following statements:

There have been no reservations in the auditor's reports of Grant Thornton LLP for the last two fiscal years reported on by Grant Thornton LLP ending December 31, 2004 and December 31, 2005. In the opinion of the Company, there have been no "Reportable Events" as such term is defined in National Instrument 51-102 Continuous Disclosure Obligations.

Upon receipt of the acceptance by PricewaterhouseCoopers LLP, Chartered Accountants, and in accordance with the requirements of NI-51-102, the Company filed a second notice of change of auditors dated October 11, 2006 advising of the appointment of PricewaterhouseCoopers LLP, Chartered Accountants, as the Company's auditors.

The reporting package in connection with the change of auditors described herein, which has recently been completed, is currently available on www.sedar.com .

Ascendant's principal business is the exploration for copper in Ecuador. The Company has two primary properties including its Junin Project located in northern Ecuador, a copper-molybdenum, gold and silver porphyry property with an inferred mineral resource of 982 million tonnes grading 0.89% copper, 0.04% molybdenum and 1.9 grams per ton of silver, at a 0.4% copper cut-off grade(1). The Company has commenced drilling on its Chaucha property located in southern Ecuador, a copper-molybdenum porphyry containing an inferred resource of 216 million tonnes with 2.2 billion pounds of copper at 0.46% and 0.03% molybdenum at a 0.20% copper cut-off grade (2)(3). Ascendant recently purchased the Telimbela copper/molybdenum property in south/central Ecuador, which project is in the early stages of exploration.
