  Recent advances in quantum simulation based on neutral atoms have largely
benefited from high-resolution, single-atom sensitive imaging techniques. A
variety of approaches have been developed to achieve such local detection of
atoms in optical lattices or optical tweezers. For alkaline-earth and
alkaline-earth-like atoms, the presence of narrow optical transitions opens up
the possibility of performing novel types of Sisyphus cooling, where the
cooling mechanism originates from the capability to spatially resolve the
differential optical level shifts in the trap potential. Up to now, it has been
an open question whether high-fidelity imaging could be achieved in a
"repulsive Sisyphus" configuration, where the trap depth of the ground state
exceeds that of the excited state involved in cooling. Here, we demonstrate
high-fidelity ($99.971(1)\%$) and high-survival ($99.80(5)\%$) imaging of
strontium atoms using repulsive Sisyphus cooling. We use an optical lattice as
a pinning potential for atoms in a large-scale tweezer array with up to $399$
tweezers and show repeated, high-fidelity lattice-tweezer-lattice transfers. We
furthermore demonstrate loading the lattice with approximately 10000 atoms
directly from the MOT and scalable imaging over $>10000$ lattice sites with a
combined survival probability and classification fidelity better than $99.2\%$.
Our lattice thus serves as a locally addressable and sortable reservoir for
continuous refilling of optical tweezer arrays in the future.
