The MEGATON prospect lies on the southeast side of Woodjam Creek, 12 kilometres southeast of the community of Horsefly and 56.5 kilometres east-northeast of the city of Williams Lake. It is approximately 1.4 kilometres southwest of the Cariboo Rand prospect (Minfile 093A 188) and 1.9 kilometres northeast of the Woodjam Southeast prospect (Minfile 093A 251).

The property lies within the Quesnel Trough which is comprised of Triassic Nicola Group marine sediments, volcanics and volcaniclastics intruded by Late Triassic to Early Jurassic dacite and monzonite-granodiorite intrusions of the Takomkane Batholith. Mineralization consists of malachite, azurite and native copper as well as local trace amounts of bornite, chalcocite, covellite and molybdenite.

The 2013 drilling program intersected traces of chalcopyrite mineralization in all 6 holes and has identified a shallowly occurring zone of weak to moderate chalcopyrite mineralization. The dominant style of copper mineralization is thin chalcopyrite± pyrite stringer veins. Common but less frequent are quartz± chalcopyrite± molybdenite veins. Drilling highlights included 121 metres of 0.11 per cent copper in hole MT13-04.

In 2021, two drill holes at Megaton encountered medium-grained quartz monzonite. In hole MT21-07, copper mineralization occurs as chalcopyrite on dry fractures and in fine quartz chalcopyrite-pyrite veinlets and was associated with a zone of phyllic (sericite) alteration. Molybdenum occurred in fine quartz veins and locally as massive (semi-massive) 3-10 centimetre quartz-molybdenite veins. MT21-07 intersected two mineralized zones, the best being 93 metres grading 0.13 per cent copper and trace gold and molybdenum from 162 metres downhole. In hole MT21-08, chalcopyrite and lesser molybdenite mineralization on dry fractures and within quartz veinlets was associated with weak to moderate phlogopite alteration of biotite. MT21-08 intersected two zones of mineralization, the first being 84 metres grading 0.15 per cent copper from 165 metres downhole and the second being 96 metres grading 0.03 per cent copper and 0.022 per cent molybdenum from 270 metres downhole (Assessment Report 39718).

In 2023, drill hole MT23-116 (Megaton) intersected 110.1 metres averaging 0.20 per cent copper and 0.01 gram per tonne gold.

WORK HISTORY

In 2012, H.J. Wahl and J. Brown-John commenced programs of mapping, silt, till and rock sampling and trenching on their Megaton claim, in an area southwest of the Cariboo Rand Landing zone (referred to as Megaton North). Strongly anomalous silt and soil values for copper and zinc and 11 test pits indicated shear zone mineralization over a 200 metre wide by 900 metre long area.

In 2013, Gold Fields Horsefly Exploration Corp. drilled 19 holes totalling 4542.6 metres on the Megaton, Woodjam Southeast and Three Firs mineral occurrences. The Megaton occurrence (Wahl and Brown-John) received 1473.91 metres of this program, in 6 NQ holes along the Megaton Option's west boundary, adjacent the the Woodjam Southeast zone (Assessment Report 34676).

In 2016 and 2020, Consolidated Woodjam Copper Corp. carried out IP/Resistivity surveys over four areas of their large consolidated property. One of these was the Woodjam Southeast zone IP grid extended onto the Megaton Option towards hole MT13-04. The IP survey of the Megaton Area and extending east from the Woodjam Southeast zone shows a broad linear chargeability anomaly on the 200 metre and 400 metre depth slices that extends 3.7 kilometres to onto the Megaton Option and towards the Cariboo Rand (Assessment Report 39382). This IP chargeability was tested by the drilling of two NQ diamond drill holes (870 metres) at Megaton in 2021. The two 2021 drill holes encountered anomalous copper mineralization, consistent with that in hole MT13-04. Below the copper mineralization, weakly anomalous molybdenum occurs along with two narrow semi massive veins in hole MT21-07 (Assessment Report 39718).

In 2022, a soil sampling program south of Horsefly road and a 2,999 line-kilometre, high resolution, helicopter-borne magnetic survey was conducted over the main mineralized corridor at Woodjam (Assessment Report 40993).

In December 2022, Consolidated Woodjam Copper Corp. became a wholly-owned subsidiary of Vizsla Copper Corp. (PR REL Vizsla Copper Corp. Dec. 13, 2022).

Vizsla's 2023 program included drilling of two holes at the Megaton zone (PR REL Vizsla Copper Corp. Dec. 5, 2023).
