Can anyone explain why Bill should be doing the Happy Dance at O'connor Creek?

Look carefully... :)

Here's why Bill should be doing the Happy Dance...

What is this map?

The map, above, is the official interpretation of the geophysical survey part of which Bill referenced in his update of O'Connor Creek.

Where are we?

The map shows the flight lines as vertical black lines. The base map is the USGS topographic map and shows section 25 on the left and section 29 and 30 of the adjoining township to the right of section 25.

What was interpreted?

The map shows anomalies. Anomalies are areas that are different than the surrounding areas. In this case the anomalies represent a correlation of magnetic and electromagnetic peaks. This identifies conductive mineralization. The round circles are where the anomalies are located along the lines.

In the post related to the O'connor Creek update, we are shown where the sampling is taking place. In this image, we can see a series of circles that form a line from right to left right across the middle of section 25. This indicates a long line of conductive mineralization that is several miles long and ends at section 25. The mineralization is bedrock mineralization running right down the creek. It is very probable that Oconnor Creek formed on a mineralized fault zone.

The conductive zone is a predominant mineralized zone called the Cleary Sequence. The Cleary sequence trends across the Fairbanks mining district.
