TORONTO, December 12, 2011. Sea Green Capital Corp. (TSXV - SGS) Sea Green Capital Corp. ("Sea Green") wishes to announce the completion of a Versatile Time Domain Electro Magnetic ("VTEM") survey over its Casa Berardi North Property located 10 kilometres southwest of the Casa Berardi Mine operated by Aurizon Mines Ltd. The survey was contracted to Geotech Ltd. of Newmarket, Ontario and consisted of 250 line kilometres with a 100 metre flight line spacing.

Sea Green currently holds a 70% interest in two properties in the Casa Berardi area of north western Quebec in joint venture with Explorers Alliance Corporation (30%). Explorers Alliance has indicated that they will be participating with the exploration program in the Casa Berardi region.

The purpose of this airborne survey over Casa Berardi North, to identify additional targets and better delineate the favourable gold bearing horizon. The final survey data when received from Geotech will be sent out to a geophysical consultant for interpretation.

Historical drilling performed on Casa Berardi North property by Hemlo Gold Mines and Glen Auden Resources in the 1990's partially outlined a gold bearing horizon over a 600 metre strike length along a major regional fault structure called the "Lac Janelle Fault" which is located near the northern margin of the Mistaouac Pluton. Historic drill results included 6.10 gpt gold over 1.5 metres and 2.39 gpt gold over 1.8 metres from hole 94-12. In addition, approximately 550 metres north of this gold bearing zone, Noranda in 1990 drill a single hole (M-90-02) which intersected 4.63 gpt gold over 3.0 metres.

In the third quarter of 2011 Sea Green acquired by staking an additional 962 hectares (21.3 sq. km.) to cover the southwest extension of the gold bearing horizon on the Casa Berardi North Property bringing its total land position in the Casa Berardi area to 2815 hectares (63 sq. km.)

Besides Casa Berardi North, the company also holds the Cancor Extension Property located adjacent to the Gemini and Turgeon Properties held by Cancor Mines Inc. and IAMGOLD.

Exploration in the Yukon on the Zeus and Zed properties was completed in the Summer/Fall but unfortunately did not bear significant economic gold values in the soil and silt samples to warrant further work on the properties. Project Manager/Project Geologist- Ryan Libke oversaw the work on the properties and collection of soil samples tested at ACME Labs. The Joint Venture with Goldspike Resources (TSXV-GSE) (formerly the Yukon Cornelius syndicate,) now currently control the Zeus and Zed claims. Goldspike has allowed Sea Green to extend the conditions of the joint venture to allow Sea Green to carry out a program on the CO property in the spring of 2012.
