This rare specimen of a rediscovery features large boxwork-like cavities lined with senegalite and various phosphates species in a limonite gossan matrix.

Senegalite is a rare aluminum phosphate. It is a hydrated hydroxy phosphate of aluminum. It is named after Senegal, the country in which it was first found to occur.[4][5]

The molecular structure of the phosphate mineral senegalite is Al
