Northern Star Announces Flow-Through Financing

Val-d’Or, Quebec, April 15, 2010 – Northern Star Mining Corp. (TSX-V: NSM, OTCQX:NSMSF) (Northern Star Mining or the “Company”) announces that it has arranged through Casimir Capital LP (“Casimir”), as lead agent, a flow-through private placement financing of up to 12,121,212 units (the “Units”) at a price of $0.33 per Unit for gross proceeds of up to $4,000,000 (the “Financing”). Each Unit will consist of one “flow-through” common share and one-half (1/2) of a share purchase warrant. Each whole warrant will entitle the holder to acquire an additional non-flow-through common share for a period of two years at a price of $0.50 in the first year and $0.60 in the second year.

A 7% cash commission and 7% agent’s options (“Agent’s Option”) will be paid to, among others, Casimir in connection with the Financing. Each Agent’s Option will entitle the holder to purchase one agent’s unit at a price of $0.33 for a period of two years from closing. Each agent’s unit will consist of one common share and one-half (1/2) of an agent’s warrant. Each whole agent’s warrant will entitle the holder to purchase an additional common share on the same terms and conditions as the warrants forming part of the Units being sold under the Financing.

The gross proceeds of the Financing will be used to carry out further exploration on the Company's Quebec mineral properties which qualify as “Canadian exploration expense” under the Income Tax Act (Canada) and can be renounced to the purchasers.

An initial closing of the Financing is scheduled for April 16, 2010.

The TSX Venture Exchange has not reviewed and does not accept responsibility for the adequacy or accuracy of this release.
