The 987-hectare Roger project is located in the Chibougamau Mining District within the prolific Abitibi greenstone belt. It is situated 5 km from the mining center of Chibougamau, Quebec and has all-season road access. A power line that serviced the past-producing Troilus copper-gold mine crosses the property and connects to the Obalski electoral distribution station located 4 km south of Chibougamau.

Enforcer has entered an option and joint venture agreement with SOQUEM to earn a 50% interest in the project.

Roger is an advanced-stage exploration property containing the Mop-II porphyry gold-copper deposit. A 2006 NI 43-101 compliant mineral resource estimate on the deposit by Scott Wilson Roscoe Postle Associates Inc. for SOQUEM totalled 3.24 Mt of Inferred Resources at an average grade of 1.61 g/t Au and 0.04% Cu for a total 167,200 ounces of gold (Jan 22, 2018 press release). The mineral resources were estimated using a 1.0 g/t cut-off grade and an average long-term gold price of US$500 per ounce.

N.B.: Enforcer considers the 2006 estimate as a historical resource estimate that has relevance to the project; however, a qualified person for the Company has not done sufficient work to classify the historical estimate as a current mineral resource and as such it should not be relied on.

Subsequent to completion of the 2006 estimate, SOQUEM drilled an additional 60 holes on the property totalling 15,456 m of diamond drilling. In 1988, an underground exploration program on the deposit included 1,177 m of underground development and 1,433 m of underground drilling in 23 core holes. In total, over 55,000 m of diamond drilling have been completed on the property.

Historical Resource Estimate

Although historically explored as a higher-grade, vein type deposit, the Mop-II is now being evaluated for its for its high-tonnage, low-grade gold-copper potential. Exploration up until SOQUEM obtained the property in 1997 focused on narrow, higher-grade shear zones within quartz-feldspar porphyry. Sampling of the historical drill holes was based on sulphide occurrences, and in the case of surface holes, only 48% of drilled meters were sampled for gold. Assaying for copper was based on the presence of chalcopyrite and was only carried out on 5% of the samples that were analysed for gold. This sampling bias is at odds with results of surface drilling by SOQUEM that report wider zones of lower-grade mineralization.

Of the 136 holes drilled prior to SOQUEM, only 9 holes from the 1988-89 program were recovered and provide the opportunity for re-assaying. To verify the results of some other historical holes, several were selected for twinning during the 2018 Phase 1 drilling program. This will also provide the opportunity for sampling along the entire length of the holes to determine what lower grade mineralization may have been missed in the historic sampling.

In addition to gold-copper porphyry mineralization, the Roger project also offers the potential for epithermal gold-silver-copper-lead-zinc mineralization as observed south of the property on the Berrigan deposit.


Mop-II Deposit

A first-phase, diamond drilling program commenced in early March and was completed with the drilling of 11 holes totalling 3,068 m. Eight holes were designed to duplicate historical (pre-SOQUEM) holes for which the core was only assayed over short intervals of quartz veins and/or mineralization and the original core is no longer available for sampling.  Two holes targeted both the North Zone near surface and the Main Zone at the -330 m level. One additional hole deepened a 2008 SOQUEM hole by 146.5 m to test the Main Zone at depth. 

Once received from the analytical lab, the results of the 2018 Phase 1 drilling will be compiled and modelled with the historical (1957-1989) and more recent drilling by SOQUEM (2008-2013) to prepare a current mineral resource estimate on the Mop-II gold-copper deposit.


Abitibi Greenstone Belt

Gold and copper were first discovered in the Chibougamau mining camp in the early 1900s. Active mining from 1953 to 2008 produced 3.2 million ounces of gold and 1.6 billion pounds of copper along with significant amounts of silver and zinc. Production was derived from three deposit types: mesothermal Cu-Au veins, volcanogenic massive sulphide and porphyry copper style mineralization.

Regional Geology & Occurrences

The Chibougamau mining camp lies at the eastern extremity of the Abitibi greenstone belt. The Archean-aged rocks of the area consist of two mafic-to-felsic volcanic cycles overlain by a sequence of sedimentary and volcanic rocks. The volcanics have been intruded by comagmatic gabbro sills, including the Doré Lake Complex, which hosts most of the copper-gold mines of the Chibougamau area, and the Cummings Complex, which hosts the copper-gold mines of the Chapais area. The stratigraphy has been folded along north-south axes, refolded about east-west axes and metamorphosed to the greenschist facies. The rocks have also been intruded by many syn-to-post tectonic tonalite, diorite, and granodiorite plutons.

Gold mineralization at the Mop-II deposit is associated with a large ENE-trending pyrite gold-bearing mineralized envelope that is ~200 m wide and at least 800 m long. The gold mineralization mainly occurs in the quartz-feldspar porphyry intrusion along 0.5 m to 20 m wide east-west trending shear zones but is also present in the rocks immediately adjacent to the intrusion. Drilling to date has intersected mineralization from near surface to 330 m depth (open).

1988 Underground Exploration Program

Exploration for gold on the Roger property began in the 1940s and the first drilling campaign was conducted in 1957. Drilling programs were limited in scope until the period 1985 to 1989, when Flanagan Inc. and Muscocho Exploration Ltd. carried out close to 24,700 m of surface drilling followed by an underground exploration program that included 832 m of ramp development, 82 m of cross-cuts, 124 m of drifting, 139 m in raises, over 1,000 m of chip sampling and 1,400 m of underground drilling in 23 holes.
The 1988 underground program was planned to test 2 of 4 auriferous shear zones that had been interpreted from surface drilling to trend northwest; however, the underground program revealed that gold mineralization was actually controlled by east-west trending shear zones. Sixty-five surface holes drilled in 1988 were also oriented to test northwest-trending structures, and as such intersected the mineralization at 45 degrees to its trend rather than perpendicular. This would have greatly hindered the geological understanding of the deposit at the time. Exploration work ceased in 1989 due to low gold prices and the property lay dormant until SOQUEM staked the area in 1997.

From 2000 to 2005, SOQUEM carried out an additional 7,500 m drilling and commissioned a mineral resource estimate on the Mop-II deposit that was completed in January 2006. SOQUEM completed 4 additional drilling campaigns between 2008 and 2013 totalling over 15,000 m.

Prior to 2018, 17 separate drilling campaigns were completed on the property totalling nearly 55,000 m of diamond drilling.
