Belmont Resources is planning is to drill a potential lode-gold deposit on its A J gold property in southern British Columbia
Drilling will target of a multi coincident geophysical anomaly overlain by diorite (intrusive?) and listwanite situated in the North Zone of the property.

The Jackpot fault directly intersects this anomalous zone providing a conduit for the hydrothermal fluids and subsequent precipitation of gold mineralization.

Listwanite and Gold Mineralization
Listwanite (carbonated serpentinite) is a term to describe the silica-carbonate alteration of serpentinite and is commonly associated with high-grade lode-gold mineralization.

The Mother Lode gold district in California and the Abitibi greenstone belt of the Superior Province of Canada are two of the most well-known examples of listwanite-associated lode-gold in North America. In general, the richest gold grades within these deposits are associated with, or in close proximity to carbonate-altered ultramafic rocks (Listwanite). Listwanite is also directly associated with several multi-million ounce gold deposits in British Columbia; Atlin, Bralorne and Barkerville.
Listwanite and Serpentinite

During the serpentinization process any gold present in the serpentine may be assimilated with secondary sulfides and/or magnetite and could be indicative by the magnetic anomalies within the property."
These opaque minerals (magnetite) are subsequently destroyed in talc-carbonate alteration zones (magnetic low features), which results in gold being released from the serpentinite wall rocks and transported in solution. The gold and silica-rich fluids are transported to higher crustal levels via faults where the change in conditions (lower temperature, pH and ƒO2) results in the precipitation of gold, quartz and sulfides. All of the historic production from the property, and the vast majority of the previous exploration, has been directed at massive sulfide and oxidized sulfide zones within listwanite.

Structurally Controlled and Diorite Hosted Mineralization

The geologic favorability for a gold resource in the North Zone area is not only related to listwanite mineralization potentially gleaned from the serpentine but also from potential concealed intrusives which are indicated by magnetic lows in the center and north areas of the property and associated with the Jackpot fault.

Areas mapped as “old diorite” may be diorite intrusions which has undergone a higher degree of hydrothermal alteration (mag low) than the adjacent serpentine (mag high). These intrusions are also coincident with geophysical and magnetic anomalies making for high priority drill targets.

A 1983 report by J.S. Kermeen, M.Sc, P.Eng stated “The most prevalent rock, at least on surface, on the property is a serpentinite believed to be derived from an ultramafic igneous rock (sill, flow or pyroclastic?)”

“The next most prevalent rock on the property is a rock given a field classification of diorite which appear to be intrusive with dikes of diorite composition cutting the serpentinite.”1.

A second apparent diorite intrusion is in the northern portion of the property. This diorite is also coincident with a strong magnetic low suggesting hydrothermal activity. This area will be further investigated for gold mineralization.

The A-J South Zone is a 1.0km mineralized gold trend which includes the Athelstan and Jackpot past producing gold mines which produced 7,600 ozs Au & 9,000 oz Ag (Minfile 082ESE047).
Along with the two former gold mines this trend includes numerous trenches, pits and adits as well as mine waste dumps. Sampling in this area has returned extensive high gold and silver results. In particular sampling of the mine dumps have returned grades as high as 1oz/ton gold and over 5 oz/ton silver.
A 2002 Report by R.E. Miller, B.Eng., P.Geo states “A potential resource of 2,000‐5,000 ounces of gold in the surface and near surface mineralized areas appears to exist within the A‐J Group based on previous trenching results and sampling of mine dumps. The identification of one to two areas of ore have been identified having dimensions of 2.0 metres thick, 15 metres in width and 90 metres in length with an average grade of 0.3 opt gold.”2
