This is a movie I watched that featured a Wild West town which is invaded by aliens. The aliens resemble giant tripods from War of the Worlds, but they appear to be purely biological. Their weapon consists of an extremely sharp blade mounted on a tail.

The townsfolk find out that the aliens seem to consume the uranium ore that the town mines. The townsfolk then come up with a plan to kill such aliens by waiting until one such alien shows up to consume the uranium ore and then detonating it with a stick of dynamite. I think this plan ends up succeeding.

Based on my recollection, I would say it is not the 2011 movie Cowboys & Aliens.

Pretty sure this is High Plains Invaders (2009).

From Wikipedia:

High Plains Invaders is a 2009 American Western science fiction television film that aired on the Syfy Channel. It is the 21st film of the Maneater Series. The film stars James Marsters.

From Horror News:

In the early 20th century, aliens of the giant metallic insect variety invade a remote Western mining town in a mission to find enough uranium to fuel their spaceship. Retired outlaw Sam Danville (James Marsters) leads a motley band against the menace. For the human survivors, the mystery of what these nightmarish invaders really are — and what exactly they want — is just the beginning of their problems.

The aliens in this film do somewhat resemble the Tripods from War of the Worlds (albeit, they're a lot smaller), and have tails with blades on them. As the synopsis above notes, they invade a remote mining town to take uranium to fuel their spaceship. In the end, the spaceship is blown up when one of the townsfolk uses a stick of dynamite to detonate a wagon loaded with uranium directly beneath it.

    "...uses a stick of dynamite to detonate a wagon loaded with uranium directly beneath it." Man, if the folks at the Manhattan project had known that was all they needed to do, it would have saved everyone a lot of trouble. Aug 18 at 12:23
  • Technically that's kind of how Fat Man and Little Boy worked. Maybe the dynamite by some incredible coincidence created a blast compression of the exact variety needed to cause implosion?

    @tbrookside - well, Little Boy didn't use implosion, and Fat Man didn't use uranium. And it seems unlikely the mine was heavily enriched U-235...

  • @JonCuster Now that you mention it, a gun-type fission device would be even easier to create accidentally! Wow, this is totally plausible now!

This sounds to me like it could be Wild Wild West (1999)

Although this is more scifi than strictly aliens, but does contain a sort of large tripod based monster.

    Monster? Are you referring to the giant robot spider? The OP said the aliens in the film they're looking for were "purely biological". Aug 18 at 10:35
  • @LogicDictates My bad, I missed that bit, it's almost certainly not Wild Wild West then if's something "purely biological"
