Why does it say Mining:false? The GPU miner is hashing at around 100 Mh/s and seems to have found 1 block.
Sorry that's a confusing bit of information. Mining:false is talking about the CPU miner, not the GPU miner. 'BlocksMined' talks about blocks mined by both the gpu miner and the cpu miner. 'BlocksMined' resets every time you restart Sia.
Blocks take 144 confirmations before you get the money. That usually takes 24 hours, but the early network is going faster (difficulty still needs to adjust - it's up 15x already but has more adjusting to do).
Check back at block height 2100 and see if you've got any coins.
