Roku 1776 byl c\u00edsa\u0159sk\u00fd kr\u00e1lovsk\u00fd dvorn\u00ed rada Jan Tade\u00e1\u0161 Anton\u00edn Peithner s Lichtenfelsu pov\u011b\u0159en pr\u016fzkumem n\u00e1plav\u016f Otavy v okol\u00ed m\u011bsta Rej\u0161tejna.

Kolem roku 1780 se d\u00e1le ne\u00fasp\u011b\u0161n\u011b pokou\u0161el o r\u00fd\u017eov\u00e1n\u00ed zlata i Ka\u0161par hrab\u011b \u0160ternberk.

Roku 1888 se v oblasti mezi Rej\u0161tejnem a Z\u00e1tav\u00edm pokou\u0161el o r\u00fd\u017eov\u00e1n\u00ed na n\u011bkolika m\u00edstech d\u016fln\u00ed podnikatel Eugen Beitl. V nejnad\u011bjn\u011bj\u0161\u00ed lokalit\u011b u obce Rade\u0161ov u Rej\u0161tejna, vybudoval v \u0159e\u010di\u0161ti Otavy 30 metr\u016f dlouh\u00e9 r\u00fd\u017eovnick\u00e9 koryto \u010dlen\u011bn\u00e9 mnoha \u017el\u00e1bky, na jeho\u017e konci se nach\u00e1zela amalgama\u010dn\u00ed j\u00edmka se rtut\u00ed. Z 1 tuny \u0159\u00ed\u010dn\u00edho p\u00edsku se mu \u00fadajn\u011b poda\u0159ilo vyr\u00fd\u017eovat 330 gram\u016f zlata a 118 gram\u016f st\u0159\u00edbra. Tyto \u00fadaje jsou v\u0161ak pova\u017eov\u00e1ny za zna\u010dn\u011b nadsazen\u00e9.<\/p>\n

Po ne\u00fasp\u011b\u0161n\u00e9m hled\u00e1n\u00ed spole\u010dn\u00edka pro pr\u016fmyslov\u00e9 r\u00fd\u017eov\u00e1n\u00ed v\u0161ak Beitl od sv\u00e9 snahy upustil. Beitlem publikovan\u00e9 v\u00fdsledky byly pravd\u011bpodobn\u011b p\u0159\u00ed\u010dinou pokus\u016f o obnovu r\u00fd\u017eovnick\u00fdch prac\u00ed v t\u00e9to oblasti v roce 1902 n\u011bmeck\u00fdmi t\u011b\u017ea\u0159i z Norimberku a Magdeburku. Pokusy o obnovu r\u00fd\u017eov\u00e1n\u00ed v\u0161ak byly brzy po sv\u00e9m po\u010d\u00e1tku ukon\u010deny bez uve\u0159ejn\u011bn\u00ed v\u00fdsledk\u016f. Zlato se vlastn\u011b nevyt\u011b\u017e\u00ed nikdy.<\/p>\n

Zlato jde z hor, jak pracuj\u00ed, pukaj\u00ed a praskaj\u00ed, zlato se postupn\u011b vyplavuje do \u0159ek a ty se znovu obohacuj\u00ed. P\u0159edstavte si sk\u00e1lu s k\u0159emennou \u017e\u00edlou, uvnit\u0159 kter\u00e9 je zlato. Odpo\u010d\u00edv\u00e1 si tam jako v konzerv\u011b. A kdy\u017e p\u0159ijde t\u0159eba -20 stup\u0148\u016f Celsia, sk\u00e1la poprask\u00e1 a zv\u011btr\u00e1, zlato se za\u010dne postupn\u011b vym\u00fdvat ven. A proto\u017ee je kujn\u00e9, p\u0159izp\u016fsob\u00ed se a rozpad\u00e1 na kousky, zlatinky, kter\u00e9 jsou vym\u00fdv\u00e1ny vodou.<\/p>\n
