Black Pine Mine (Combination Mine; Black Pine Tailings; Black Pine Dump), Flint Creek Valley, John Long Mts, Philipsburg District (Flint Creek District), Granite Co., Montana, USA

Located approx. 14.5 km NW of Philipsburg.

Note: "The boleite attributed to the Black Pine mine actually came from the bricks of the Bi-Metallic Mill (Red Mill) in Philipsburg, Montana and are a reaction of the lime from the mortar in the bricks with the copper and silver left from the milling, smelter process. These specimens were found in the 50's or 60's and made their way into collections as boleite with the location as Black Pine, Montana." (Brent Thorne information)
