I am not sure which page you are referring to, but they told me in the message they sent me to receive an explanation, that they would have added this information to the website.
Probably the deposit page

We as campaign participants don't have to go through that page which is probably why you didn't see it, but any making a deposit with notice that 0.001 BTC minimum deposit which also applies to the mining campaign, this was also confirmed in their message to you (100k sats = 0.001
BTC) your deposit/leftover was 0.00046059
BTC which doesn't qualify for APR.
@GazetaBitcoin, was your balance over 0.001
BTC?
