Yes, but would you agree it functions more as an Ice-type than Weavile? Weavile seems like a generic Dark-type to most people...I would believe so as I've never heard of it. Mamoswine is generally considered to be better than Weavile because Ice+Ground is an excellent offensive combo and it allows it to only take 12.5% from Stealth Rock
BTW Scizor, how come the OU tier has so many Steel-types? What made this? "Best defensive type in the game" may be one reason, but...
