Predictive Discovery's (ASX:PDI) potential merger with Robex Resources (ASX:RXR) gains scale, financial strength, and a strong presence in Guinea's "highly-prized" Siguiri Basin, according to a Thursday Euroz Hartleys note.

PDI and RXR on Thursday said they entered into an amendment to the Oct. 5 arrangement agreement, under which Predictive will acquire all of the issued and outstanding common shares of Robex, exchanging 7.862 ordinary shares of Predictive for each Robex share via a statutory plan of arrangement, according to separate filings with the Australian bourse.

The research firm said that the revised PDI-RXR merger plans provide PDI shareholders with higher MergeCo interest, and RXR shareholders with slightly diluted interest, but it should be noted that larger shareholders are on both sides, hence a similar outcome.

Euroz Hartleys maintained its speculative buy rating on each of PDI and RXR, with price targets of AU$0.80 and AU$6.59, respectively.
