HotCopper Highlights, Week 18: Imugene’s letter to investors; Dimerix & Dateline

Good Afternoon and welcome to HotCopper Highlights for the end of Week 18, 2025, I’m Jonathon Davidson. In this segment we wrap up the stocks you were watching most this week, let’s get into it. 

Starting off with the most viewed, 

Dateline Resources shot to the top of the boards on Friday after its Colosseum rare earths mine got a direct mention from President Trump on his Truth Social account, pushing shares up nearly 150% to 2.2 cents per share. Investors are betting the Presidential shout out will bring good things. 

Elsewhere, Peninsula Energy attracted eyes this week as the company announced its Non-Executive Chairman was walking out the door. That’s not too unusual of itself, but with shares still suspended ahead of a flagged guidance downgrade, investors were paying attention.

Finally, established biotech favourite Telix sunk earlier this week attracting attention as the FDA effectively rejected one of its drugs under development, despite the company pointing to a prior early-stage approval. 

And so what about the most discussed? 

Another biotech stock, Dimerix, shot up and generated chatter late week as the company won a licence to commercialise its drug DMX-200 in the US. That drug aims to treat a rare kidney disease which is often fatal. 

Elsewhere, Andromeda Metals gained attention as the company flagged it had made a breakthrough in the production of high purity alumina. The often overlooked metal has myriad applications in the world of hi-tech.

Finally, Imugene caused a lot of chatter when it issued a letter to shareholders addressing common criticisms of the company. Imugene acknowledged that it burns a lot of cash but says that’s normal for biotech, that it can’t control short sellers, and that progress on multiple fronts has been slowed down due to complex matters requiring more time spent ‘at the hospital.’ For context, one year returns are down over -70%.

That’s HotCopper Highlights for this week, I’m Jon Davidson, have a great weekend and we’ll see you on Monday.
