27 July 2011drilling result▲ Good

First seven holes of the 2011 program at the Sulphurets deposit on Seabridge's 100%-owned KSM project in northwest British Columbia, drilled specifically to move about 3 million ounces of higher-grade inferred gold that the 2011 study counts as waste into the reserve category; hole S-11-34 cut 64.6 metres at 1.28 g/t gold and 0.13% copper. The company said the intercepts were wider and better grade than expected and should increase reserves.

30 June 2011capital raising announcement▲ GoodMajor

Closed the Royal Gold private placement: 1,019,000 shares at C$29.44 for C$30 million, a 15% premium. Royal Gold also got an option over a 1.25% gold and silver royalty on KSM for C$100 million, exercisable only after full permits and project financing.

What it means for a shareholder

1.0m new shares at C$29.44 to raise about C$30.0m. Shares on issue before the raise aren't in the record, so the dilution can't be worked out.

20 June 2011resource reserve update▲ GoodMajor

Filed the 2011 KSM prefeasibility study, prepared by Wardrop, which identified two higher-throughput scenarios said to improve the economics substantially. This is the study whose reserves - 38.5 million ounces of gold and 10 billion pounds of copper - anchor everything that follows.

9 June 2010regulatory community update● Neutral

The federal environmental agency (CEAA) released its proposed scope for the KSM environmental assessment and opened a 30-day public comment period. Seabridge says it can now keep to its plan of filing the assessment application with both governments in late 2010, which is later than the September 2010 date given in November 2009 (an inference: the schedule has slipped slightly). The release also restates the March 2010 preliminary feasibility study reserves of 30.2 million ounces of gold, down from the 38.9 million ounces of measured and indicated resources they were derived from.

13 Jan 2010resource reserve update▲ GoodMajor

KSM measured and indicated resources rose 13% to 38.9 million ounces of gold and 17% to 10.0 billion pounds of copper, with Mitchell alone at 33.7 million ounces - which the company called the largest gold deposit ever found in Canada.

Signed a non-binding letter of intent to sell its Nevada exploration properties, including Castle-Black Rock, to Constitution Mining for more than US$7 million in staged cash and other consideration.

25 Nov 2009regulatory community update▲ Good

The BC Environmental Assessment Office issued its Section 11 Order for KSM, setting the scope and procedures of the environmental assessment and naming which Treaty and First Nations the government must consult. Seabridge says permitting is on schedule, the two-year baseline program is nearly complete, and the application document is due in September 2010, ahead of the preliminary feasibility study scheduled for March 2010. It says nearly $55 million has been spent on KSM so far, about $8 million of it on environmental studies. This starts the permitting thread that ends with the 2014 BC certificate.

First economic study of KSM: a 30-year mine recovering more than 19 million ounces of gold at a cash operating cost of negative US$11 an ounce after base metal credits, and US$233 an ounce in total. The number that has justified holding KSM ever since.
