Dynacor has 100% ownership of its Acari property in Peru

Montr�al, Qu�bec, April 17, 2007 - Dynacor (TSX: DYN) is pleased to announce that it signed an agreement for the buyout of the remaining 20% interest of its subsidiary Minera Dynacor del Per�, in compensation for the issuance of a maximum of 2,200,000 shares from its share capital. As per an agreement signed in August 1996, Dynacor already held the mining rights and the ore processing plant of the Acari property through its subsidiary Minera Dynacor del Peru S.A. held at 80% by the Company and 20% by Peruvian shareholders. With this transaction, the Company acquires all of the property's assets. This acquisition is subject to precondition approval of the Toronto Stock Exchange.

HISTORY
The Acari 1 property, located 428 km south of Lima, is made up of one mining claim covering a surface area of 800 hectares. Dynacor also holds an option on four other claims that add up to a further 3,010 hectares. This important property hosts several major veins including the "Principale" and "Carnero" veins, which are visible over 800 metres vertically and are more than 2 km long and have widths of up to 2-3 metres at certain points.

In 2006, the Acari mine generated an operating profit of $988,564 from the 14,312 ounces of gold produced from the custom milling operations. At the end of 2006, the mill capacity was enlarged from 60 to 100 t/day and will be increased again in 2007 in order to process 130 t/day.

OUTLOOK
Dynacor plans to continue increasing the plant's production capacity to reach, in 2008, 25,000 ounces of gold annually by custom milling operations. Since the beginning of 2007, the average gold production from custom milling was 1,713 ounces monthly.
