The Gaza 1 (North) occurrence is located south of Witches Brook and southeast of Lily Lake, at an elevation of approximately 1290 metres.

The area is situated along the contact between Guichon and Chataway varieties of the Highland Valley phase of the Lower Jurassic Guichon Creek Batholith. The Guichon variety, on the southeast side, is medium- to coarse-grained granodiorite to quartz diorite. The Chataway variety is younger granodiorite, also medium- to coarse- grained with slightly less mafic minerals. The area is cut by faults and fractures of variable orientations.

Locally, a 6 to 15-metre wide mineralized shear zone, strikes 075 to 080 degrees east, with a steep dip to the south and has been traced for approximately 260 metres. Mineralization consists primarily of bornite with lesser chalcopyrite, chalcocite and minor molybdenite. The shear zone is cut by a younger set of fractures striking 040 to 060 degrees. Alteration minerals include sericite, chlorite, malachite, biotite, epidote, minor potassium feldspar, clay and zeolites (stilbite, heulandite).

In 1984, a diamond drill hole (E-6) encountered significant copper oxides and bornite with minor chalcopyrite and chalcocite at depth yielding 0.20 per cent copper over its final 54.86 metres, including intercepts of 0.28 per cent copper, 0.004 per cent molybdenum and 2.3 grams per tonne silver over 18.29 metres and up to 0.33 per cent copper over 3.05 metres (Assessment Report 13318). Two other holes yielded up to 0.16 per cent copper over 9.15 metres, including 0.27 per cent copper with 2.8 grams per tonne silver over 3.05 metres in hole F-3 and 0.09 per cent copper with 0.011 per cent molybdenum over 3.05 metres in hole G-6 (Assessment Report 13318).

In 1963, Sheba Copper Mines Ltd. exposed and trenched a mineralized zone on the Gap 1-2 claims to the south. In 1964, Gaza Mines Ltd. completed an induced polarization survey on the area and four drill holes on the Gap 1-2 claims. In 1966, Canadian Superior Exploration Ltd. and Jericho Mines Ltd. completed a program of silt and soil sampling, geological mapping, trenching and a 57.6 line-kilometre induced polarization survey on the area. In 1969, Tremar Mines completed a 50.5 line-kilometre induced polarization survey. The following year, 11 percussion drill holes, totalling 1035 metres, were completed. In 1971, Highmont Mining Corp. optioned the property and completed 17 diamond drill holes, totalling 2538 metres, and 30 percussion drill holes, totalling 2926 metres. In 1972, a program of geological mapping, an induced polarization survey, six trenches, five percussion drill holes and three diamond drill holes were completed on the property. In 1974, Highmont Mining Corp. completed a program of soil sampling on the area. In 1979, Highmont Mining Corp. and New Jericho Mines Ltd. completed three diamond drill holes, totalling 61 metres. Later the same year, Highmont Operating Corp. completed a drilling program including 2 churn drill holes, totalling 174.0 metres, 11 percussion drill holes, totalling 165.0 metres, 2 rotary drill holes, totalling 134.0 metres and 5 diamond drill holes, totalling 504.0 metres, on the Gaza and Jericho claims. In 1981, a further 11 rotary drill holes, totalling 87.8 metres, were completed. In 1984, a program of soil sampling and 10 percussion drill holes, totalling 1002.8 metres, were completed.
