There is Khumus on Rikaz

And Malik and Ibn Idris said, “Rikaz is the buried treasures in the Pre-Islamic Period and Khumus is compulsory on it whether the treasure is small or large, but the mines are not considered as Rikaz.” No doubt, the Prophet (ﷺ) ﷺ had said, “There is no Zakat on minerals. And Khumus is compulsory on Rikaz.” ‘Umar bin ‘Abdul ‘Aziz took five portions out of every two-hundred from minerals. And Al-Hasan said, “Khumus is compulsory on Rikaz found in the land owned by non-Muslims, but if found in the Muslim territory there is only Zakat on it. If one finds a Luqata (fallen property) in the territory of the enemy, he must announce it publicly. And if it belongs to the enemy, then Khumus is compulsory on it. Some people considered minerals as Rikaz similar to the buried treasures of pre-Islamic period.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَعَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ الْعَجْمَاءُ جُبَارٌ، وَالْبِئْرُ جُبَارٌ، وَالْمَعْدِنُ جُبَارٌ، وَفِي الرِّكَازِ الْخُمُسُ ‏"‏‏.‏

Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "There is no compensation for one killed or wounded by an animal or by falling in a well, or because of working in mines; but Khumus is compulsory on Rikaz."
