Dear Agoracom Family,
I want to thank all of you for your patience with us over the past 48 hours and apologize for what was admittedly a botched launch of our new site.
As you can see, we have reverted back to the previous version of the site while we address multiple forum functionality flaws that inexplicably made their way into the launch.
To this end:
1.We have identified 8 fundamental but easily fixable flaws that will be corrected in the coming week, so that you can continue to use the forums exactly as you've been accustomed to.
2.Additionally we will also be implementing a couple of design improvements to "tighten up" the look and feel of the forums.
Have a great Sunday, especially those of you like me that are celebrating Orthodox Easter ... As well as those of you who are also like me and mourning another Maple Leafs Game 7 exit ... Ugggh!
Sincerely,
George et al
StrataGold completes economic assessment at Mar

STRATAGOLD ANNOUNCES POSITIVE PRELIMINARY ECONOMIC ASSESSMENT ON THE MAR-TUNGSTEN DEPOSIT, YUKON
StrataGold Corp. is releasing a positive National Instrument (NI) 43-101 preliminary economic assessment (PEA) on its 100-per-cent-owned Mar tungsten deposit, located within the Dublin Gulch property, Yukon Territory. The PEA was produced by SRK Consulting (U.S.) Inc.
PEA highlights:
Assumptions:
Mining
Mining of the Mar tungsten zone will be a conventional open-pit truck and shovel operation, with the necessary support equipment. Mining operations are characterized by a moderate stripping ratio pit consisting of skarn-hosted tungsten mineralization located on a plateau 2.5 kilometres west of the Eagle zone gold deposit. It has been assumed that a mining contractor will execute the mining of the mineralized material and waste material. The preliminary pit design was determined to be approximately 0.5 kilometre in diameter, 250 metres deep, with a volume of 27.6 million cubic metres. The operation would originally start with three 100-tonne trucks, plus support equipment, with additional units added over the life of mine to make up fleet requirements.
PIT DESIGN RESULTS Mill total throughput 9,868,551 tonnes Mill throughput per year 1,020,000 tonnes (3,000 tonnes per day) Waste total 66,071,293 tonnes Strip ratio 6.70:1 WO3 grade 0.33% Contained WO3 70,856,775 pounds
Process and infrastructure
The indicated process flowsheet at the Mar tungsten deposit would include:
Access to the property is via road 35 kilometres north of Mayo via Highway 2 and then proceeds along the South McQuesten Road for 46 kilometres, of which the last 25 kilometres is not maintained but in good repair. Mayo is located 350 kilometres north of Whitehorse. An existing 69-kilovolt-ampere power line runs within 20 kilometres of the project.
Updated Mar tungsten deposit resource statement (1)
The mineral resource has been restated from the company's news release in Stockwatch on Oct. 16, 2008, and has resulted in an overall increase of 89 per cent to the indicated resource from the resource statement reported in Stockwatch on Jan. 15, 2008. The resource statement previously announced in Stockwatch on Oct. 16, 2008, contained a company conversion error of tungsten to WO3 grades on 2008 drill results and the grade shell was reduced from 0.1 per cent to 0.05 per cent WO3.
WO3 MTUs Resource Total % WO3 Contained WO3 (metric tonne category tonnes grade (*) (pounds) units (xx)) Indicated 12,700,000 0.31 86,200,000 3,909,000 Inferred 1,300,000 0.30 8,900,000 403,000 (*) A cut-off grade of 0.10 per cent WO3 was used for this resource statement with a categorical indicator technique to develop a grade shell of 0.05 per cent WO3 used to limit the projection of mineralization. (xx) An MTU is defined as one-100th of a metric tonne or 22.05 pounds.
Notes:
Recommendations
The Mar tungsten deposit has excellent opportunities for significant resource expansion. The mineralization is defined over an 800-metre strike length and remains open in several directions. Exploration drilling is warranted on the north and south extensions of the mineralization, and further downdip to the west. A program of 4,840 metres of diamond drilling is recommended to delineate the limits of mineralization, which can be recovered by open-pit mining. An additional 2,650 metres of diamond drilling (not included in budget) is recommended to define exploration potential to the west and on other targets in the area.
SRK recommends the commencement of a prefeasibility study, which would include additional metallurgical testwork, geotechnical drilling and data collection, groundwater monitoring and dewatering wells, and environmental monitoring and additional baseline work.
Program Cost (in millions of U.S. dollars) Exploration drilling 4,840 metres -- 25 holes 3.20 Metallurgical studies 0.25 Geotechnical drilling (four holes) 0.50 Tailings trade-off study and site geotechnical studies 0.20 Groundwater monitoring and dewatering wells (six holes) 0.60 Environmental monitoring and baseline work 0.75 Prefeasibility study (12 to 18 months) 1.25 Total recommended work plan 6.75
The company deems the equity markets all but closed with respect to financing near-term exploration and development activities. In this environment, StrataGold continues to explore strategic alternatives, and will continue to seek options that are in the best interest of its shareholders and, in particular, the advancement of the Mar-Tungsten deposit.
We seek Safe Harbor.
