Chukotka is the most northwestern part of Russia, close to the Bering Strait. The majority of Chukotka is inhabited by the local Chukots. A nomadic tribe who live mainly of reindeer herding. Apart from these nomadic people there a few small settlements.

Located in the basin of the Omolon river. I'm not sure about the exact locality, but the Omolon mainly flows through Chukotka, so I put it here.
Although Chetigun river is frequently mentioned as Axinite locality, I believe it is the same locality as Pribrezhnoye, located near the mouth of the Chetigun.
Iul'tin is a hydrothermal tin-tungsten deposit in the Ekeotap Khrebet. The deposit consists of three groups of sedimentary-metamorphic rocks. Lower Carboniferous crystalline schists and limestones, Upper Permian shales, sandstones and siltstones of the Iul'tin group and Triassic shales siltstones and sandstones of the Amguem group. In this lay Triassicgabbro intrusions as well as Cretacous granodiorites of the Pravo-Iul'tin massif and Upper Cretaceous granite of the Iul'tin massif. The Iul'tin mine was opened in 1954 and extended in 1959.

The Karal'veem deposit became most of all known for single find of a specimen with multiple 1cm gold crystals.

The Palyansk deposit is located in Upper Triassic terrigenous sediments (sandstones, siltstones and shales). The shales contain siderite and organic matter. The west side of the deposit is covered with Cretaceous volcanogenic rocks and the sediments are cut by various dykes of lamprophyre, granodiorite and aplite, as well as Quartz-carbonate veins.

The Plamennoye deposit is located at the edge of the Okhotsk-Chukotka volcanic belt. The deposit consists of various lower Cretaceous volcanic rocks, such as rhyolites and tuffs. These are cut by subvolcanic granitoids, andesites and late Cretaceous diorites. The rocks are subsequently folded and hydrothermally altered.

The Pribrezhnoye deposit is a skarn located near the mouth of the Chetigun river. The Quartz occurs here as green quartz because of Actinolite inclusions. Japanese twins are also known from here.

Translated as 'Ore Hill' Rudni Sopka is the type locality of selenostephanite.

So far I could not find any references of this locality. I have a Ferro-Axinite from this locality in my collection, which looks similar to the Chetigun material.
Located close to Iul'tin. There are numerous other Svetloye deposits all over Russia!

Tenkergyn is located at the northern shore of the Chukot sea just east of Mys Schmidta. Tenkergyn is greisen deposit well known for it's large orange scheelite crystals. In some older publications Tenkergyn is known as the Volchye deposit.

The Val'kumei deposit is located near Pevek on the coast of the East Siberian Sea. The deposit consists of a mesozoic granite intrusion in the Chukotka terrane.
