What are the flaws bout RDM ? What i miss?

On my relentless search for Silver ( Gold pgm)Developers/Explorers world wide beeing investet in 45 world wide i ran across RDM .
Back ground info :
I rode Deg 14bag sold Ard 4bag ( low grade and eqvoz Not OZ made me leave ) 4bagged Svl ( left due Water probls and hard tJunior explorer Red Metal 100% owns the Maronan silver-lead and copper-gold project in the Carpentaria province of Queensland, which has been estimated to contain inferred resources of 30.8Mt at 6.5% lead with 106g/t silvero mine in fut high cost mine built etc ) but still am heavy invested in Auc and Ivr !!! Sitting 4bags both - NO INTENTION TO. SELL. + small invest in Ipt .
Now i wondered if i could find another Silver play in Australia and research brought me thru small caps. To Rdm !
I couldnt believe what i saw :
.
What ??????????????? There is another Australian with 100,000000++ oz Ag !! Are you kidding me ???
In all other HC Coppersilver stocks threads Ivr Ard pym svl are constantly Cross mentioned . You cant miss either one !!!
Even Pnx (16,5moz) got mentioned .
Why has RDM only doubled from march lows ? Why does a 100moz Ag Explo has a 27mil $aud MC ? ivr has 42Moz and MC 60mil$ !!!
Please point out all the problems RDM has ? Before i invest in somthing that seems too be " to good to be true"
Thx
