It's felt quite difficult to get them ill admit, but I also started actively looking for them more recently so that may be why im noticing exactly how rare they can be.
I think I may have found 1 or 2 out of smashing rocks in total. I’ve had the game for a couple weeks and hit the rocks every day (also have TT’d a couple days here and there) apart from that I got lucky with the island tours and landed at the gold rock/scorpion nightmare place. But I sold all 8 or 9 of those before I realised that gold tools may need gold
i don't know if the spawn rates have gone down, but i've always struggled to collect them. i don't really use them very often though, so it's not a problem!
I actually borrowed my brother's switch for a temporary second island recently, and no, in the span of a couple hours I got 10 gold nuggets.
I got 2 gold nuggets from 1 rock twice, and it felt like I got one almost every time I hit a gotdamn rock. it was wild. since I don't hit rocks anymore on my main switch I can't vouch for that but still
but also dupers are making them worth dirt now, you can get hundreds of them from Nookazon for the low low price of a rocking horse
I actually thought they'd increased the drop rate since 1.2. I have gotten way more gold ore recently, especially on islands. Last night I got two from the same rock. (I almost immediately got ganked by a scorpion naturally.)
The companion guide mentions there is only a 1% chance to get gold ore from rocks. Both on your island and on mystery islands. I can't say if it has been changed since then though.
I haven't noticed a difference. They've always been rare. Unless you get the gold nugget mystery island, where you're guaranteed to get 8 gold nuggets from the rock, the spawn rate is only 1% chance. It doesn't matter if it's your island or a (non-gold nugget island) mystery island.
