The brand new junction box needs a brand new 14-3 -with-ground cable going to the updated panel where you have a brand new 2 pole 15 amp double wide breaker set inside for that brand new 120/240 volt branch circuit.
An existing ungrounded outlet box may have a single conductor ground wire run from it (and possibly daisy chaining through other existing outlet boxes on the same ungrounded branch circuit and) over to the panel ground bus bar (or to the braided ground wire to the ground rod if that is closer). Then 3 prong receptacles may be put in the affected existing outlet boxes.
If the basement is unfinished then all of the new receptacles need ground fault circuit interrupter protection. This may be accomplished either with a GFCI breaker for the applicable branch circuit or a GFCI receptacle unit. For receptacles daisy chained on a 14-2 (or 12-2) circuit, the first receptacle can be a GFCI unit and the other further on can be regular receptacles.
GFCI receptacles may be substituted on non-grounded circuits without the need to add grounding.
"Bonded connection" is a redundancy. A bond is a connection, specifically an essentially resistance free connection in the sense that if A is bonded to B and B is bonded to C then A is bonded to C. For electrical purposes, the quality of the bond is significant such as the bond from the panel to the ground rod must be a wire of at least 6 gauge copper and sections of copper plumbing may not constitute part of that connecting path.
