Lately there have been some changes and a lot of confusion regarding the Abydos mine at Anasco.
Players are able to mine platina at Abydos starting from lvl 70.
However to be able to find Syriet ore drops you will need lvl 85+, drops of Obsidian ores have a requirement of mining lvl 100.
There is a very slight increase of drop rates with lvl increments, but this might be hard to notice as it's a very small difference.
Hope this clarifies it and avoids further confusion.
We are in the stickiest situation since sticky the stick insect got stuck on a sticky bun.
