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 river

GRAPHICS-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 gravity spill out

Materials with a high specific gravity sink to the bottom”

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

Flow of the river

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!!!
