CALGARY, ALBERTA--(CCNMatthews - Nov. 1, 2006) - PrimeWest Energy Trust (TSX:PWI.UN)(TSX:PWX)(TSX:PWI.DB.A)(TSX:PWI.DB.B)(NYSE:PWI) (PrimeWest or the Trust) wishes to inform its unitholders of an announcement made by the Honourable Jim Flaherty, Canadian Minister of Finance late yesterday detailing proposed changes to the taxation of Canadian income trusts.

The relevant measures announced include a proposed tax on distributions paid by publicly traded income trusts and limited partnerships, and will result in less after-tax cash being available for payment to all unitholders. As an existing income trust it is important to note that these measures will not apply to PrimeWest until January 2011. Under the Government's proposal the existing tax treatment of distributions will remain in effect during the four-year grace period to 2011.
