Is it possible ? Or no i found that app on Windows Store
Yeah its possible to mining on windows phone. 
But its waste time and energy, you just spent batteries and your income form that its very little.
Better you join signature campaign and post in windows phone.
Yes even with powerful computers with latest GPU or CPU with multi core, people are not able to find their mining profitable. So, with a phone, definitely we can not catch the profit with mining. better do faucets, you will see some profits.
