What is this mystery rock?

One of our viewers has sent us some pictures of a substance, asking for help identifying it.

Thought I'd share it here on the blog to see if anyone can help.

The sender (called Matt) said: "I have been watching your videos and I was wondering if you could help me identify a mysterious rock I found when I was young.

"I live in Canada, Ontario, and have never found a similar rock like this before, I am hoping you can help me identify what it is.

"After many hours of searching the net, the closest resemblance I could come up with is raw Titanium.
