  We use a Chandra X-ray observation of the gravitationally lensed system
MGB2016+112 at z=3.273 to elucidate presence of at least two X-ray sources. We
find that these sources are consistent with the VLBI components measured by
\citet{Spingola19}, which are separated by $\sim 200$ pc. Their intrinsic 0.5
-- 7 keV source frame luminosities are 2.6$\times$10$^{43}$ and
4.2$\times$10$^{44}$ erg s$^{-1}$. Most likely this system contains a dual
active galactic nucleus (AGN), but we possibly are detecting an AGN plus a
pc-scale X-ray jet, the latter lying in a region at very high magnification.
The quadruply lensed X-ray source is within $\pm$40 pc (1$\sigma$) of its VLBI
counterpart. Using a gravitational lens as a telescope, and a novel statistical
application, we have achieved unprecedented accuracy for measuring metric
distances at such large redshifts in X-ray astronomy, which is tens of mas if
the source is located close to the caustics, while it is of hundreds of mas if
the source is in a region at lower amplification. The present demonstration of
this approach has implications for future X-ray investigations of large numbers
of lensed systems.
