These mineral specimens came from the Platinum fields in the far Nth of Hokkaido Japan & we are not 100% certain what they are ; our field manuel on minerals from these Platinum fields is a book from the Sapporo Rock museum with lots of clear color plates which indicate this metallic rock has gold content mixed in it.
The rocks comefrom deep within stream beds in areas of very high content
of gold 24k and also platinum.
What was remarkable about where these rocks came from was the very small areas they could be found 20 meters by 80 meters & then no more of these kinds of rocks :
If there is a knowledgable Geoligist out in the collectors on these web pages we would love to hear from you.
