Tin them. The broken traces may be tricky. Being that that area inserts into the slot. Use very small wire.

The proper fix is find an scarifical AGP card with same contact finger design, nick and cut tracks, peel off damaged contacts, same time do same to salvage AGP card, cut longer track attached to the contact finger, scrape bare copper first, nick a edge and peel off a good contact, using high temp epoxy glue them down over lapping original bare track and wait for epoxy to cure. Once done, bridge the bare track to tail end of replacement track where contact is with small wire and solder, flux.

This is professional track repair where there is absolutely no choice. This is done on irreplaceable expensive boards too.

I have done peeling the tracks before to do repairs.

Absolutely cannot have tinned contact in high speed circuits as this can cause intermittent issues as soldered layer oxidizes over time.

Cheers,

Actually because AGP slots do use alternating "staggered height pinchers" in the slot, those thin traces above the fatter bottom conductor part never get touched by the pinchers so you could use a thin (meaning able to paint a very non-thick line) good conductive paint (silver based, not graphite based) or even silver based "wire glue"(if done correctly) on the traces that go inside the slot. The trick will be to keep your created trace as flat as possible.
For above the slot in the green enameled area you can tin, solder wire, whatever... because they are just like any other board trace but as pentiumspeed mentioned over time the solder can degrade...
just a thought and much easier than stripping traces off a donor card. forgot to mention: I would NOT try to solder/Tin or use any wire that goes down into the AGP slot.

Thank you all for your input. Not particularly proud of how this turned out, but I had to quickly check if the card is at least a bit alive so pentiumspeed's method was out of the question (mainly because I'm lacking the high-temp epoxy and the experience 😁 )

At the initial check-up I found 4 broken traces, but more of them broke up at the boundary between the gold-plated finger and plain copper when I went over them with the soldering iron, so it ended up with 13 bridge wires (not all were needed, but I put them on all traces that looked very bad). Some of the larger traces were ok with just tinning. The end-result fits nicely in the socket, and it has survived at least one insertion and removal cycle 😁
The Voodoo's alive, but it's not very healthy:

This means more work to do, checking for discontinuities around the upper four RAM chips. I'll come back with an update in the next few days.

For such small work, that is pretty good.

Nice job fixing that, it looks quite tidy 😀
I have a Voodoo 3 that's got the same mess on the screen, but that's my fault for flexing the card fitting a screw-on heatsink. I think I detached one of the BGA pads for the memory potentially.
