Northern Star Partner Britannica Reports New Results

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Oct. 25, 2006) - Northern Star Mining Corporation (TSX VENTURE:NSM) option/joint venture partner, Britannica Resources Corp. has provided further results from the Revillard project, located northwest of the town of Malartic, Quebec, on a property subject to an option/joint venture agreement (Press Release March 21, 2006).

The new gold-copper discovery is located some 300 meters northwest and on strike from the previous gold discovery on the project (see press release July, 18).

A series of grab samples taken along the Kewagama/Blake River group contacts in an intensely altered and iron rich zone returned the following values:



Gold (g/t) Copper (ppm)
Rev 276 12.60 2,280
Rev 277 1.72 3,550
Rev 278 0.46 901
Rev 279 8.03 3,500
Rev 280 1.19 1,005

- All samples were assayed using a standard AA finish at ALS Chemex in
Val-d'Or, Quebec. Robert Gagnon, P.Geol. is the qualified person on the
project.


The initial surface gold discovery was made this past summer over a magnetic high anomaly coincident with a number of induced polarization anomalies.

The magnetic anomaly, reflecting an iron rich altered zone is over 900 meters in length and 300 meters in width and is open in both directions. The anomaly is located on the Kewagama/Blake River contact, one of the best potential geological sections in the area, with the Kewagama sediments to the north and the Blake River basic and felsic volcanics to the south.

The initial discovery revealed an intensely altered and sheared zone consisting of chloritic, ankeritic and silicate alteration and enrichment, with mineralization consisting of pyrite, chalcopyrite and free gold.

Britannica undertook further exploration some 300 meters to the northwest and discovered the continuation of the alteration zone, with the added presence of copper mineralization in the form of bornite and malachite as copper bearing minerals.

The presence of copper gold mineralization within a magnetic high anomaly, coincident with I.P. anomalies and located at the Kewagama/Blake River contact demonstrates the high potential of the property.

Finally Britannica completed on Infini TEM geophysical survey over the discovery areas, and results indicate the presence of a strong conductor, coincident with the magnetic anomaly, which may correspond to massive sulphide mineralization of the VMS type (volcanogenic massive sulphide). A number of discrete IP (induced polarization) anomalies from previous work carried out by Northern Star Mining are also coincident with the above.

The company is very excited by these significant results obtained from the start up of the exploration programs, by its option/joint venture partner. The Revillard project is a joint venture consisting of 21 claims comprising 880 hectares whereby Britannica can earn 50% by expending 1.5 million dollars in exploration expenditures over a 4 year period. Britannica has also issued 500,000 shares to Northern Star Mining Corp for the option agreement.

The project is located on an important contact horizon (Kewagama/Blake River) which, some 10 km to the west contains the following producing gold and base metal mines: Laronde Agnico Eagle (http://www.agnico-eagle.com/), Bousquet, Doyon and a number of past producing mines including O'Brien, Kewagama, and Cadillac. To the east the past producing Camflo Gold Mines is also located on this horizon.

A Quebec government report states, "...the Eastern Blake River group emphasizes the strong gold potential in these rocks. This also shows that certain areas located very near established mining camps, such as the Doyon-Bousquet-Laronde camp, still remain unexplored," (ref. M.R.N. report 2004 32 D/7).

Interpretation and drill core analyses continue from the diamond drilling on the Midway project.

Results will be released as available.
