What might this be?

0 votes

alt textalt textI recently found this nugget while metal detecting in the Willamette Valley, Oregon (northern Oregon). Based on several characteristics from much of what I've read a lot points it being Platinum, but not totally convinced. While history notes some Platinum discovered nearby long ago, no evidence found of any recent discovery. What might be the best way to know for sure?

It certainly has the look of possibly being platinum. However, I never heard of that locality being associated with platinum. Some questions: Is it very heavy? Was it found in a placer deposit (i.e. in a stream bed)? What color is its streak? Are there similar pieces nearby?

It was found in an alluvial deposit in a flood plain of a local river. The streak is silver gray with shine. It is heavy, 15 grams. Rough measurement 4x1.8 cm.

Platinum is definitely a possibility - which would mean a lucky strike! Do you have any way to test the specific gravity?
