What is this old PC truck game?

Question

I've begun to recall a game I played as a child with my brother, and I can't remember what it was called for the life of me. The reason I'm asking for identification is because I remember how much he loved it. Christmas is coming up and I want to see if I can get it for him, along with a few other PC games we loved as kids, and rig up some hardware that can still run the game as a present for him. I would really appreciate if you guys can help me out in time for the holidays!

Here's everything I can remember about this game:

1. It was an old PC game, probably for Windows XP, since I think that was the computer we had at the time. For reference on the time frame, we also owned the old Lego Island games, the other half of my potential Christmas present.
2. It involved what I believe were either Tonka trucks or other non-branded construction vehicles. I seem to remember you could drive them around a 3D or 2D environment, destroying and building things. You could control dump trucks, cranes and other heavy construction equipment.
3. There was definitely a space or moon base level where you could drill into walls and find secret tunnels using a drill truck of some kind, and I think the goal was to find a certain amount of a mineral which was hidden in the walls. I remember it being one of the more difficult stages, so it probably occurred later in the game.

Does anyone remember the name of this game? I've done a bit of research around the Internet but nothing I can find jogs my memory. If this question is too vague, I'll see what else I can remember about it and add more information.

Answer 1

There's Tonka Construction 2 (1999) and similar games in the series, including one called Tonka Space Station, but that one looks like a racing game, not a mineral hunting game.
