Red Chris and Havieron deliver outstanding growth and infill drilling results

At Red Chris, drilling continues to expand the known higher grade mineralisation intersected at East Ridge, with this new discovery adjacent to the East Zone continuing to return high grade intercepts, supporting the potential for resource growth.

RC705^^ returned 254m @ 1.0g/t Au & 1.1% Cu from 718m, including 80m @ 1.6g/t Au & 1.4% Cu from 852m. This hole is located 100m above RC678 (previously reported) and demonstrates continuity over 300m vertically.

RC727 returned 346m @ 1.1g/t Au & 0.79% Cu from 1,046m, including 56m @ 3.5g/t Au & 1.8% Cu from 1,336m. This hole is located 100m below RC688 (previously reported) and is the highest-grade intercept from East Ridge.

As previously noted, East Ridge is located outside of Newcrest's Red Chris initial Mineral Resource estimate. Mineralisation remains open to the east and at depth, with ongoing drilling to define the extent.

At Havieron, growth drilling continues to extend high grade mineralisation outside of the initial Inferred Mineral Resource extent, while infill results validate, and in some places upgrades, the current model interpretation.

New growth drilling continues to assess the depth extents of the South East Crescent. New intercepts show an increase in both grade and thickness with increasing depth. HAD133W1^^ has returned 133m @ 7.0g/t Au & 0.05% Cu from 1,446m, including 55.9m @ 9.7g/t Au & 0.04% Cu from 1,449.5m, ~250m below the Inferred Mineral Resource extent. The SE Crescent now has a vertical extent of over 900m.

Results received from infill drilling support the modelled grade and thickness within the South East Crescent zone Mineral Resource extents. The results also support the continuity of the high grade, and in some places upgrade the zone, as represented by HAD117W6 which returned 120.4m @ 10g/t Au & 0.66% Cu from 764.6m. This is the best gram metre intercept drilled to date at Havieron (Au_ppm x intercept length of 1,204 gram metres).

Melbourne, Australia--(Newsfile Corp. - October 27, 2021) - Newcrest Mining Limited (ASX: NCM) (TSX: NCM) (PNGX: NCM) Newcrest Managing Director and Chief Executive Officer, Sandeep Biswas, said, "We are really excited by the latest results from our growth and infill drilling programs at Red Chris and Havieron. At Red Chris, we reported the best high grade intercept from our new East Ridge discovery of 56m @ 3.5g/t gold and 1.8% copper from RC727. At Havieron, the infill drilling program continues to demonstrate high grade within the deposit, with the latest intercept returning a significant 120.4m @ 10g/t gold and 0.66% copper from HAD117W6 in the South East Crescent zone, which is the best gram metre intercept drilled at Havieron to date. The growth drilling results also continue to extend the high-grade mineralisation outside of the initial Inferred Mineral Resource estimate at Havieron."

"Newcrest is at a very exciting stage in its organic growth journey and the exceptional drilling results today highlight the significant potential for resource growth at both Red Chris and Havieron," said Mr Biswas.

Red Chris, British Columbia, Canada(2)

Red Chris is a joint venture between Newcrest (70%) and Imperial Metals Corporation (30%) which is operated by Newcrest.

The Brownfields Exploration program is focused on the discovery of additional zones of higher grade mineralisation within the Red Chris porphyry corridor, including targets outside of Newcrest's initial Mineral Resource estimate. During the period, there were up to eight diamond drill rigs in operation. A further 29,388m of drilling has been completed from 24 drill holes, with all drill holes intersecting mineralisation (except twelve drill holes which were dedicated geotechnical holes). This contributed to a total of 196,074m of drilling from 161 drill holes since Newcrest acquired its interest in the joint venture in August 2019.

At East Ridge, located adjacent to the East Zone, drilling is ongoing with 14 holes completed and six in progress. The follow up drilling is being completed on a nominal 100m x 100m grid to determine the footprint of the mineralisation and demonstrate the continuity of the higher grade mineralisation.

Results for the reporting period include:

RC705^^ (drilled 100m above of RC678 previously reported) returned 254m @ 1.0g/t Au & 1.1% Cu from 718m, including 80m @ 1.6g/t Au & 1.4% Cu from 852m.
RC708^^ (drilled 100m above of RC700 previously reported) returned 232m @ 0.16g/t Au & 0.26% Cu from 754m.
RC709^^ (drilled 100m west of RC678) returned 166m @ 0.4g/t Au & 0.49% Cu from 788m, including 30m @ 1.1g/t Au & 1.1% Cu from 902m.
RC713^^ (drilled 100m above RC705) returned 190m @ 0.26g/t Au & 0.41% Cu from 574m, including 28m @ 0.57g/t Au & 0.74% Cu from 712m.
RC718^^ (drilled 100m east of RC700^^ previously reported) returned 298m @ 0.33g/t Au & 0.45% Cu from 820m, including 52m @ 0.67g/t Au & 0.75% Cu from 1,062m.
RC719 (drilled 100m above RC709 previously reported) returned 252m @ 0.26g/t Au & 0.36% Cu from 678m, including 10m @ 0.58g/t Au & 0.93% Cu from 732m; and
RC727 (drilled 100m below RC688 previously reported) returned 346m @ 1.1g/t Au & 0.79% Cu from 1,046m, including 56m @ 3.5g/t Au & 1.8% Cu from 1,336m.
Drilling to date has demonstrated continuity of the East Ridge zone (>0.4g/t Au and >0.4% Cu, >1g/t AuEq[3]) over dimensions of 400m high, 400m long and 125m wide, with the higher grade (>0.8g/t Au and >0.8% Cu, >2g/t AuEq3) over 300m high, 300m long and 100m wide.

East Ridge is located 300m east of East Zone and is outside of Newcrest's initial Mineral Resource estimate, supporting the potential for resource growth over time. Mineralisation is open to the east and at depth and extends the eastern side of the porphyry corridor as shown in Figures 1 and 2. Follow-up drilling is in progress to further define the extent and continuity of this high grade mineralisation.

A step out hole, RC701^^ drilled 700m east of East Ridge has extended the porphyry corridor beyond the limit of the East Ridge drilling. This hole returned 206m @ 0.2g/t Au & 0.49% Cu from 1,816m. The intercept is one of the deepest on the property. Drilling is planned for the zone between East Ridge and RC701 to search for additional high grade zones.

Approximately 50,000m of growth-related drilling is planned this calendar year from eight drill rigs.
