Linarite is a well-known and highly sought-after lead-copper sulfate mineral, prized for its intense blue colour. This specimen features a vug lined with lustrous, light to dark electric-blue linarite crystals, set against a matrix that consists partly of massive metallic galena with malachite spots on the reverse side. The Beaver Occurrence, located 21 km northwest of Kaslo, British Columbia, lies on the south-facing slopes of Beaver Mountain. This silver-lead-copper-bearing vein system hosts argentiferous galena as the primary ore mineral, all set within an alteration assemblage of malachite, azurite, anglesite, linarite, pyrite, and quartz. From a collector’s perspective, the Beaver Occurrence is extremely difficult to access, and the finest linarite crystals were likely collected in the 1920s. Today, little remains of interest for field collectors, making specimens from this locality increasingly rare. However, the vivid blue colour and the rarity of linarite ensure its continued desirability among mineral collectors. This specimen exemplifies both qualities, making it a noteworthy piece from an uncommon locality for the species.
