Geo in January had a switch to a new blockchain. The 1st link is some different coin, it's supply is 20milion and last transactions occured over 30 days ago. 2nd link (chainz) is part of old blockchain that is developer abandonded and coins from that chain can only be manually swapped with developers if coins were present on the wallet before the swap occured - therefore transfering old coins to a wallet and requesting manual swap is not going to be honored.

Only official exchanges trading Geo coins are Bittrex and Cryptopia, recently there were rumors of other exchanges offering Geo, but it has not been fully confirmed yet. Yobit used to trade Geocoin, but they did not participate in the swap and they remained trading old coin, those are worthless as they cannot be swapped.

As Geo is part of Ubiq network it uses it's block explorer - https://ubiqscan.io/contract/0x500684ce0d4f04abedff3e54fcf8acc5e6cfc4bd
