The Congress (Lou) occurrence is located immediately west of the Congress mine (092JNE029), approximately six kilometres northeast of Goldbridge.

The Lou zone consists of a 12-metre-wide shear striking north to northeast along a Tertiary feldspar porphyry dyke which intrudes the contact between basalts and metasediments/cherts and argillites of the Mississippian-Jurassic Bridge River Complex (Group). The zone has been traced for 440 metres along strike. Potassium/argon analysis of the dyke suggests an age of 67.1 Ma +/- 2.2 Ma (Fieldwork 1985).

Massive, banded and disseminated stibnite, tetrahedrite, arsenopyrite and pyrite occur in narrow quartz veins and altered wallrock within the shear zone. Two potential ore shoots have been identified with grades up 12.686 grams per tonne gold over 3.4 metres (Assessment Report 15728). Other portions of the zone contain lower grades over narrow widths although alteration envelopes are locally up to 30 metres wide. Ankerite, mariposite and realgar (kermesite) are also reported.

Indicated reserves (proven geological) of open pittable oxide ore are 34,466 tonnes grading 2.74 grams per tonne gold. Inferred reserves (probable geological) of open pittable oxide ore are 89,793 tonnes grading 2.4 grams per tonne gold (George Cross News Letter #26, 1986).
