Puzzle Quest Galactrix

If you're anything like me, you'll still need to do this at the end of the game, despite having mined hundreds of thousands of credits worth in Beta Centauri. The easiest way to grind out the last few "successful" mining operations is to play the early asteroids with lower requirements.

The easiest combination I found is in the top left of the galaxy map, in the starting systems. If you hit each of the below asteroids, the first one will be ready for use again once you complete the fourth one, so you can just travel in a little circle between systems, only going for the easiest asteroids.

These are the easiest asteroids I could find:

Ceti: BK409B
Erebus: E3CF36J
Talus: XK786T
Elea: PH549D

Barring some bad luck, you should be able to hit all or most of these every "lap" around the galaxy, making the 10 successful operations easy to acquire. This is quite a bit easier than trying to do it in Beta Centauri or anywhere else that has difficult asteroids.

Mining is a matching mini-game where you must match 3+ gems of a specific type and have to "mine" a certain number of each material to count as a "success". If you manage to get the total amount of all required materials, you get double of each material mined as a bonus. If unsuccessful, you still get to keep what you mined as a consolation prize.

TIPS:
1. Asteroids reset after you mine three other asteroids, successfully or unsuccessfully. Use this to your advantage!

2. Use the direction of matching to your advantage. Make the gems pull away from the side of the screen with the most materials, increasing your chance to match more later. You are also awarded more material for Nova and Supernova matches, which are more likely when matching this way.

3. There are the most asteroids on Beta Centauri (five total), which is close to Terra, although these can be challenging to mine successfully.

4. You need to complete (mine all required materials) from ten asteroids total. You can mine the same one multiple times, and the ones close to the beginning are the easiest. So just fly around the beginning areas and mine the easy ones until you get ten successes if you want this quickly.

EXTRA CREDIT: Don't forget to sell your extra materials for quick credits or save them for crafting items. You do have limited capacity to carry them depending on your ship. Some factions offer more for certain materials (price in green) and less for others (price in red).

Simply mine at 10 asteroids.

Tip: Mine as many asteroids as you can that are around the starting galaxies. As these should be slightly easier.

Tip: You can mine the same asteroid as many times as you like, but you must mine at 3 others before the it becomes mine-able again.

Edit: You MUST fully mine each of the 3 resources on the asteroid for the mining to count towards your 10.
