A valid IMA mineral species

Name:

for Andries Frederik Lombaard, (August 28, 1877 Burgersfort, Southern, LP, South Africa - October 06, 1954 Burgersfort, Lydenburg, Transvaal, South Africa) who "was instrumental in the discovery of the Merensky reef". He was prospecting for gold on his farm Maandagshoek No. 148, found a few specks of a heavy white metal, which he at once suspected might be platinum.
