Started the 2011 drill program at KSM.
Announcements, explained
Each one in plain English, with the numbers worked through for a shareholder.
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.
22 Dec 2009resource reserve update● Neutral
Confirmed the KSM prefeasibility study was on schedule for the end of March 2010 and that design changes recommended by Thyssen Mining were likely to cut capital and operating costs.
3 Dec 2009asset acquisition disposition● Neutral
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. That sale did not happen: the same Nevada ground went into Wolfpack Gold with Golden Predator in 2012, for shares.
3 Nov 2009drilling result▲ Good
Kerr drilling completed the 2009 upgrade exercise across all three KSM deposits, with a new resource estimate promised before year end.
27 Oct 2009drilling result▲ Good
Mitchell drilling was expected to upgrade in-pit inferred resources and to improve the ore-to-waste ratio by reclassifying material previously counted as waste.
14 Oct 2009drilling result▲ Good
Sulphurets drilling came in better than expected and was expected to convert substantially all the remaining in-pit inferred material to measured and indicated.
30 July 2009resource reserve update▲ GoodMajor
An updated economic study for KSM cut initial capital 10% and unit operating costs 11% against the 2008 version.
25 June 2009asset acquisition disposition▲ GoodMajor
Agreed to sell Red Mountain to BonTerra Resources for C$12 million - $7.0 million cash and a $5.0 million convertible debenture. Red Mountain comes back to Seabridge later and is optioned out twice more, to Banks Island in 2012 and Revolution in 2014.
7 Jan 2009drilling result▲ Good
The last two holes of 2008 confirmed a higher-grade breccia zone extension at Sulphurets.
22 Dec 2008drilling result▲ Good
Final 13 Mitchell holes of 2008 - two exploration, three infill and eight geotechnical - with an updated resource estimate expected in February 2009.
19 Dec 2008asset acquisition disposition● Neutral
Duplicate filing of the same 15 December 2008 release reporting the completed Noche Buena sale.
17 Dec 2008asset acquisition disposition▲ GoodMajor
Completed the Noche Buena sale and was paid US$25 million in cash, funding feasibility work at KSM and Courageous Lake without issuing shares.
1 Dec 2008resource reserve update▲ GoodMajor
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.
10 Oct 2008asset acquisition disposition▲ GoodMajor
Agreed to sell Noche Buena to the Fresnillo-Newmont joint venture for US$25 million cash at closing plus a further US$5 million if commercial production ever starts, with the money earmarked for feasibility work at KSM and Courageous Lake. A project bought for US$4.35 million two years earlier.
19 Aug 2008drilling result▲ Good
First nine holes of the 2008 program infilled the eastern side of Mitchell and tested for a northeast down-dip extension.
16 June 2008drilling progress report● Neutral
Began a 15,000 metre program at KSM to upgrade and expand Mitchell.
22 Feb 2008resource reserve update▲ GoodMajor
The rebuilt Mitchell estimate moved more than 55% of the gold into the indicated category, where the whole of the 2007 estimate had been inferred - the confidence upgrade that makes a deposit financeable rather than merely large.
28 Jan 2008asset acquisition disposition● Neutral
Noche Buena's resource grew 14% after 33 holes and about 8,000 metres of 2007 drilling, and Seabridge said the project would be sold - bought in 2006 to be improved and resold, not mined.
22 Jan 2008resource reserve update▲ GoodMajor
First independent resource estimates for the Kerr and Sulphurets zones, completing the three-deposit picture at KSM alongside Mitchell.
19 Dec 2007drilling result▲ Good
The final 11 holes of 2007 confirmed the upgrade and expansion at Mitchell.
5 Dec 2007drilling result▲ Good
Nine more holes pointed to a significant upgrade and expansion of Mitchell's gold and copper resources.
13 Nov 2007drilling progress report● Neutral
Finished the 2007 Mitchell program and commissioned a new resource report.
22 Oct 2007drilling result▲ Good
The first eight holes of a 15,000 metre summer program extended Mitchell north, south and at depth.
22 Oct 2007drilling result▲ GoodMajor
Hole M-07-35 extended Mitchell at least 300 metres deeper, running 682 metres of continuous mineralisation from surface averaging 0.92 g/t gold and 0.24% copper and ending in the best grades yet seen on the property.
15 May 2007resource reserve update▲ GoodMajor
Filed the first technical report on a gold-copper resource at Mitchell and set out a 2007 drill program to grow it.
31 Jan 2007drilling progress report● Neutral

17 Nov 2006drilling result▲ GoodMajor
Seven more holes at Mitchell expanded the newly recognised gold-copper porphyry and confirmed grade continuity comparable to operating mines. Mitchell had only just been drilled for the first time, five months after Seabridge bought back full ownership of Kerr-Sulphurets.

Started the summer drill program at Courageous Lake.
