Hi,
I'm a newbie to detecting and the forum. I found something quite similar on my first time out with my new tesoro micromax. It is extremely heavy and attracts magnets. After a lot of rooting around on the I-net I found that one test is to rub the object on an unglazed area of pottery, like the bottom of a coffee cup. If it leaves a mark like a pencil, it's a "meteorwrong". In my case it left a red mark indicating my find was composed of hematite. If it leaves a black mark it's another earth mineral, but I forgot the name. I deleted the "bookmark" for the website so I can't vouch for its credentials, now, but I was certainly persuaded at the time. Hope this helps.
