Subject:  Services contract based on the DIAGNOS’ CARDS application to be used
on Tonkin and Limo properties and large scale regional area, in North
Central Nevada, for gold, silver and copper

Dear Rob,

As per our last conversations, it is my pleasure to submit to you this proposal regarding your Tonkin and Limo properties and the regional signatures for gold, silver and copper. We reviewed the check list of data you kindly provided us.  With the information we gathered from the conversations we had, we were able to evaluate the amount of time that will be needed and the work to be done.

The service we will provide will result in prospecting maps and a detailed anomaly report based on MAP INFO or OASIS software, outlining the potential targets for gold, silver and copper discoveries on your properties:  Tonkin and Limo and large scale regional area in North Central Nevada.

CARDS application service

CARDS assist scientists and professionals in their search for natural resources.  CARDS use MCubiX-KE’s artificial intelligence and pattern recognition algorithms to learn the “signatures” or “finger prints” of high-potential resources areas and automatically detect similar sites across unexploited regions.  The result is this powerful tool that allows prospectors to concentrate time and exploration budgets to search in high-potential areas.

The use of CARDS is simple.  CARDS requires two types of data sets: a training set, used to discover the signature or fingerprints of highly profitable regions (compared to unprofitable ones), and one or many surveys describing the territory that is prospected.  The final output is a map or layer that indicates the regions where economical resources are likely to be found.

Benefits

· Significantly reduce your decision cycle time

· Derive increased knowledge from your survey data investment

· Continuously learn from your prospecting efforts

· Make better use of your exploration funds

· Significantly reduce your drilling activities thus saving your joint venture major expenses

Business Contract

DIAGNOS will run the CARDS application on the data provided by US Gold with a view to identifying mineral targets on the properties. This right to use service fee is based on a one time cost of $195,000 CDN for two properties and the regional signatures (3 signatures – 1 regional and two specifics) in North Central Nevada of which $75,000 CDN will be paid up front and is non refundable, the remaining $120,000 CDN will be paid by US Gold prior to the final delivery of the report. Furthermore, 100,000 common shares of US Gold will be paid as a success bonus to DIAGNOS on every new economical discovery on DIAGNOS targets (Economic discovery is defined as the positive feasibility study of the property).

If US Gold’s intention is to acquire claims outside its owned claimed area then DIAGNOS would also receive an additional success bonus in the form of a 2% NSR on all unclaimed stakes acquired using the DIAGNOS technology. US Gold will have the opportunity at all time to buy back 1% (representing half of the NSR) for $1 000 000 CDN.  If US Gold should acquire properties that have already NSR attached to them or if US Gold should joint-venture with other companies on properties with those conditions, the bonus on economical discovery will be in shares and of 500 000 common shares.

Process

1) Step 1-CARDS will be run on the area of study (approximately 15,000 square kilometres property package) giving you a regional signature for the three metals: copper, gold and silver.

2) Step 2- CARDS will then be ran on Tonkin and Limo (640 square kilometres) that will give a local signature on each of your properties.

Delivery date:  on or before February 28^th, 2008, if the contract is signed within ten days.
