IMPORTANT: KEEP SLIDES SPACIOUS AND SIMPLE-Review the information in the Unit 5 module about simplicity of PowerPoint. Convert the words on each slide to short phrases (2 to 4 words for each bullet point), so that you follow the 7x7 rule. -Slide 3: AVOID displaying entire quotes word-for-word, unless they are quite short. (the quote on slide 5 is OK) -Slides 7,8 & 9 are too crowded. Reduce the long points to a few words. example: -wide-mouth; -set into riverGRAPHICS-Can you add a diagram of a sluice box?
Prospecting Presented by Andrew L. Johnson
Prospecting: different forms that anyone can use! Panning And Sluice Boxes
What is Panning? • Definition: looking for gold by hand • Soil is “gently agitated… gold sinks to the bottom... • Materials with low specific gravityspill out • Materials with a high specific gravity sink to the bottom” http://www.mine.mn/Gold_Pan.htm
How to Pan for Gold Water-dirt ratio Panning techniques: vary Objective: clean rocks from sediment/dirt Ideal: square of water
Location • State regulated • In streams and rivers • “Where the trout is that’s where the gold is” (Sam from Armadillo Mining Co.) • Black sand • Behind big rocks
Safety • Water : • Never go alone • Be aware of rapids • … sink holes • … flashfloods • … quickly moving water • … first aid kit • Mountaineering: • Never go alone • Bring food • … sunscreen • … water • … personal protection • … first aid kit
Sluice box • What is a sluice box? • Wide mouth set into the river • This concentrates the gold
How does a sluice box work? • Construction: • Miners moss • Riffles: low spots in the flow pressure
Process/steps • 1. classify (sort) soil • 2. Place into river • 3. Manage water flow • 4. Place soil mixture into sluice box • 5. Afterwards, place into bucket for panning
Why and when to use sluice box: • State regulations vary • Use to simplify work • Saves hours of work by hand
Conclusion • Gold panning: fun outdoor activity! • Any age can do it! • Easy to learn! • Great family activity! • Give it a try! • And… you might hit the mother lode!!!
