October 3, 1823: A German-language newspaper in St. Petersburg first reported chemical analyses of 'white gold' as platina.
In the Fall of 1824 the amount of platina recovered was yet unknown, but historical data suggests an annual yield of 33 kilograms in 1824. The first major platina placer discovery was in May, 1824; the final Uralian caravans with appreciable amounts of the metal arrived in St. Petersburg by sledge around February 1825.
The seasonal port of St. Petersburg typically remained frozen and closed to export commerce until April/May. Although the port opened on 5 April 1825, flooding perhaps delayed normal business for several weeks longer. Therefore, at the earliest, the first significant quantities of Russian platina (1824) may have reached Paris and London markets after June 1825.

Reported 14 November in Franfurt Am Main and 18 November, 1824 in Kaiserlich-Königlich privilegirter Bothe von und für Tirol und Vorarlberg, (Western Austria) :
Leaves Public Report from St. Petersburg 22 October 1824: According to reports, is expected before the end of this year, from the Ural gold mines, especially the Goldsandmäschereien, 200 poods, or 8,000 pfund of gold. part of the crown, but mostly individuals belonging. This significant mass, against 3,280 French kilograms, and beneath which there is sometimes Platina, is worth about one million ducats. At the beginning of this century, the annual yield from all over America to 17.291 kilograms, including those of Brazil : 6,873 kilograms. So Russia now gives about half as much gold as Brazil, and it is significant growth in the near future be expected. The processing of gold-washing has prompted several mine owners, to reduce the less profitable processing of iron and copper-rich, since Russia is now a major producer of copper, so this seems to expect a rise in copper prices can be.

1827: The major discovery was in 1825, but lesser placers with some platina were discovered in the Autumn of 1824. Russian Platina may have started arriving in Western Europe in the Winter of 1824, or by the Summer of 1825.
If the Pt was 538.2 ozt and the Au 37,390 ozt., only 1,180 kilos.
