When you find shale in a gold mine, and you see the soft grey talcum like material between layers of shale, kind of greasy to touch, that's called pug. Or Fulcon.

I found a near 2 gram nugget in this type of material a week ago. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin :D" loading="lazy" data-shortname=":D" /></p></blockquote><p></p>
