World Copper Confirms Two Porphyry Copper Targets at Escalones Project
Vancouver, October 5, 2021 - World Copper Ltd. (TSXV: WCU) (OTCQB: WCUFF) ("World Copper") announces exploration results from the northern targets at the Escalones Copper project ("Escalones" or the "Escalones Project"). Over a one-month period in the first half of 2021, World Copper collected 440 samples from three targets north of the main deposit at Escalones as part of a rock sampling and mapping program, and the results outline two significant porphyry copper targets.
Key Points
- Surface sampling programme confirms two copper-porphyry targets and one skarn target to the northeast of the main Escalones deposit.
- The Rio Negro target produced five samples grading over 1% Cu and multiple samples returning over 0.5% Cu. It is considered a priority porphyry copper target for future drill programmes.
CEO Nolan Peterson commented, "The results from our surface sampling program, carried out earlier this year at Escalones, confirm that Escalones has the potential for multiple significant copper porphyry deposits in addition to the main resource. Data from the sampling program will be used in the near future to plan out the next phases of our exploration at Escalones on the Mancha Amarilla and Northern Targets."
The Northern Escalones Targets
Geochemical sampling and mapping has now been completed by World Copper on a cluster of three distal copper targets (the "Northern Targets"), located eight to ten kilometres north of the main Escalones deposit and within the 162 km2 Escalones land package. Field work at the Northern Targets confirmed the large anomalies are intense quartz-sericite, argillic and gossanous alteration of porphyritic and granitic intrusions, as well as skarn in volcanic and sedimentary units (Figure 1). The Northern Targets have significant potential, with surface alteration zones on the same scale as that of the main Escalones deposit. Ridge and spur character rock sampling at an average spacing of 200m has defined two porphyry centres that are now considered drill targets. Rio Negro is the primary target, with excellent copper mineralization at surface and will be the priority for further exploration. The eastern target, Argüelles Este, is larger and more deeply weathered, and more sampling will be carried out to determine its potential. Sampling of the third target, Argüelles, was limited, and further work programmes by the Company are expected to follow up on this work.
Rio Negro Target
The Rio Negro target is a 2x2km argillic and quartz-sericite alteration zone within dacite/monzonite porphyries intruding clastic sedimentary rocks. Copper oxide mineralization is most apparent in the centre of the alteration where multiple samples returned over 5000 ppm (0.5%) copper, with five samples returning over 1% copper (Figures 2 and 3). This central area covers an area 800x1000m and will be a focus of more detailed geochemical sampling and mapping this field season.
Argüelles Este Target
The Argüelles Este target is a very large argillic and gossanous alteration zone two kilometres southeast of Rio Negro. The geochemical anomaly generated by the sampling is roughly three kilometres in diameter. Sporadic anomalous copper and molybdenum occurs along the western third of the anomaly, where sandstone and interbedded gypsum horizons are intruded by coarse feldspar-porphyry dikes similar to those as the main Escalones deposit. Associated anomalous metals suggest a higher level of erosion in a more deeply weathered system compared with Rio Negro, so more of the lithocap is preserved. A large (one kilometre) central area of the anomaly remains to be sampled and mapped.
Argüelles Target
Extensive skarn and calc-silicate alteration form a rugged, high ridge almost three kilometres long at the Argüelles target. Sampling was restricted to the accessible bases of the ridge, where a few samples on the west side returned values >1000 ppm Cu with anomalous Mo and Ag. The focus at the Argüelles target is narrow, high-grade mineralization, and this target will require more detailed sampling to determine the significance of the results.
Sampling and Assay Procedures; Quality Control and Quality Assurance
Character rock chips were collected within a 4m diameter circle every 200m along a traverse, mostly along ridges and spurs when topography allowed, mostly from outcrop but in places from talus beneath inaccessible outcrops. For quality assurance and control, field blanks were inserted every 20 samples and field duplicates (resampling at the same location) taken every 20 samples. The 4m character sample field duplicates have a precision of ±44%. Two georeferenced photos of each sample were taken and used to verify to the extent possible the assay results, sample locations and general geology.
Sample bags were stored in rice sacks, secured with zip ties, and delivered to ALS Patagonia S.A. in Santiago, Chile. Multi-elements were assayed using the ME-MS61 package, which includes 4-acid digestion and ICP-MS finish; samples with >10,000ppm copper were re-assayed using method ME-OG62 with an ICP-AES finish. Gold was done by method Au-ICP21, in which a 30g sample is fire-assayed and finished with ICP-AES.
Readers are cautioned that surface sampling results reported here should be viewed primarily as a guidance for future exploration drilling. Surface sampling is prone to sampling bias and is not necessarily a reliable indicator of mineralization at depth
