  • Ore sorting results materially increased head grades and decreased tonnage:

  • ▪ Gold grade increased by 41.6% from 15.34g/t to 21.71g/t Au.

  • The tonnage was reduced by 33.7% with a negligible loss of grade.

Corporate

  • Initial financial commitment of US$500k for acquisition of Colosseum Gold Mine completed.

  • The Company’s shares were consolidated on a 1-for-25 basis, following shareholder approval.

  • At the end of the quarter, the Company’s cash balance was $8.025 million. Post quarter end, the Company raised a further $4.1 million at $0.09 per share.

BP Minerals wholly owned subsidiary Amselco LLC carried out the historical exploration program at the Colosseum Gold Mine prior to the introduction of the JORC Code. The exploration work, resource and reserve estimates were completed to a high standard and independently reviewed by outside firms but cannot be relied upon for reporting mineral resources or reserves. There is no guarantee of replicating BP Minerals results that are discussed in this announcement.

ASX Release 26 July 2021

Colosseum Gold Mine, California

In March 2021, Dateline entered into a binding Agreement with LAC Minerals (USA) LLC, a wholly owned subsidiary of Barrick Gold Corporation, for the acquisition of 100% of Colosseum and will acquire 83 mining claims that host the Colosseum Gold Mine and surrounding areas, totalling approximately 1,600 acres[1] .

The Colosseum Gold Mine is located in the southern section of the Walker Lane Trend in California, USA. The Walker Lane Trend Hosts numerous substantial discoveries including the Corvus Gold owned 1.7Moz Mother Lode deposit and the 6.5Moz Castle Mountain gold mine owned by Equinox Gold (located 50km to the Southeast of Colosseum). In July 2021, AngloGold Ashanti submitted a proposal to acquire Corvus Gold for US$370 million (A$496 million).

The primary activities for the June quarter were reviewing the extensive historical literature, reports and plans on the Project in order to compile a digital database.

BP Minerals data review

During the quarter, the Company reviewed historical reports and data for the Project. Colosseum was originally discovered in the early 1970’s, with the production of ~344,000 ounces of gold between 1988 and 1993 from two open pits. At the time of closure, the gold price was at a cyclical low below US$350/oz. No exploration has been undertaken at site over the past 25 years.

Geology and mining of the breccia pipes

The development of the breccia pipes at Colosseum is interpreted to have occurred ~100my ago with the intrusion of felsic magma into the Pre-Cambrian sedimentary basement rocks. This event is regionally extensive with felsic dyke outcrops exposed over a distance of 10km between Colosseum and the Mountain Pass Rare Earth Mine to the south-east.

The West and East breccia pipes have a tear-like appearance in plan view, each measuring ~800ft x 400ft (245m x 120m). Both pipes are connected by a narrow dyke. The East pipe has a relatively consistent grade vertically of ~1.3g/t Au, whereas the West pipe has more variability, with grades ranging from ~2.0g/t Au up to 4.4g/t Au (refer Figure 3 below).

ASX Release 26 July 2021

Depth potential identified

Dateline reviewed many technical reports, maps, sections, and speeches prepared by former management of the Colosseum Gold Mine covering the period from 1970 to 1993.

In several of the reports, the authors describe the drilling of two diamond drill holes (DDH-1 and DDH-2) in 1972 by Draco Mines, with both drilled to ~3,000 feet (~915m). Both drill holes targeted a porphyry molybdenum deposit thought to lie beneath the pipes and not gold. Draco Mines intersected the rubble breccia pipes at 2,600 feet (790m) below the surface.

The reference to the rubble rock breccia at depth is significant as the rubble breccia is the primary host of gold bearing sulphide mineralisation at Colosseum. Reports of the rubble breccia continuing for a further 1750ft (530m) below the known 850ft (260m) of mineralisation offers a compelling target for further assessment.

BP modelling and assessment

BP defined a resource for Colosseum of 1.1Moz Au based on 169 reverse circulation holes drilled to a depth of up to 1,000 feet below surface. The resource was estimated to 800 feet depth for the East Pipe and 900 feet for the West Pipe, both using a 0.5g/t Au cut-off in a kriged model.

The original Feasibility Study completed in 1984 envisaged an 8.5year mine life, with 12,146,000 short tons at a grade of 0.064oz/st (2.20g/t Au) for 777koz Au to be extracted over the Life of Mine (LOM). The Feasibility Study was based on a forecast gold price of US$450/oz Au.

Mining commenced in January 1988 and ceased in July 1992 at Colosseum with some stockpiled material processed through to May-1993. The gold price was under US$350/oz at the time the Colosseum mine ceased production.

A review of records indicates that there was ore remaining in the pits at the time of closure.

Rare Earth Potential

Post quarter end, the Company announced that a review of USGS data had highlighted a coincident thorium and potassium radiometric anomaly 8km along strike from the Mountain Pass Rare Earth mine, the only operating rare earth mine in the US (Figure 4).

The Mountain Pass carbonatite is a thin linear body that trends NNW, along strike from Colosseum.

Importance of Thorium and Potassium in REE Exploration

Elevated concentrations of the elements: Thorium (Th), Uranium (U) and Fluoride (F) compared to regional background abundances are useful reconnaissance indicators for geochemical exploration of REE’s. Sodium (Na) and Potassium (K) are also important indicators as they are believed to control precipitation of REE’s in and around the margins of carbonatites (such as that seen at Mountain Pass).

Next Steps

Dateline is currently digitising the significant volume of plans and sections in order to build a comprehensive database of the Project.

The Company is planning to complete the acquisition from Barrick in Q3 and prepare plans for an extensive core drilling and soil sampling program.

ASX Release 26 July 2021

Gold Links Gold Mine, Colorado

Gold Links hosts a swarm of high-grade narrow gold veins over more than 5km strike length and a kilometre across strike. Historical mapping and drilling coupled with the Company’s own exploration work has confirmed mineralisation is extensive throughout the Project. Dateline’s 100% owned Lucky Strike Mill will be used to process material from the Gold Links Mine.

Mobilisation of Mining Contractor

During the quarter, the Company appointed a mining contractor that has mobilised equipment to site and has commenced development of a 1km decline with 4.0m x 4.3m dimensions. The decline will act as a haulage and exploration tunnel, from which the 2150 and West gold veins will be drill tested.

The decline will link up with an existing drive at a lower elevation, which will provide a second escapeway for underground personnel and enhance mine ventilation. The decline work is expected to be completed in the fourth quarter of the 2021 calendar year.

Underground Diamond Drilling

The underground diamond drill crew mobilised to site and commenced drilling in July 2021. The drilling company will undertake 4,000 metres (~12,000 feet) of underground drilling from within the decline (Figure 7).

The diamond drilling will be located approximately 50-75 metres away from both the 2150 and West veins, which will enable them to complete an anticipated 2-3 drill holes per week. Underground drilling is expected to be completed during the December quarter.

Ore Sorting

The Company completed a Gold Links ore sorting program with TOMRA to assess the potential of upgrading the ore prior to further processing through the Lucky Strike mill.

A total of 849kg of material was transported to the TOMRA ore sorting facilities in Sydney. Two tests were conducted using both laser and XRT sorting technology with the XRT technology proving to be a better fit for the Gold Links Project.

Ore sorting testwork

The ore sorting testwork was completed to determine the suitability of the Gold Links mineralised material to be upgraded using advanced ore sorting technology provided by TOMRA Sorting Australia.

These results are considered to be “proof-of-concept” tests by TOMRA and were conducted on a representative sample of mineralised material collected from Gold Links.

A total of 849kg of mineralised material was collected from Gold Links, with an aggregate grade of 15.34g/t Au. Further details of the sample preparation are provided below and in Table 2.

The ore sorting procedure requires an initial set-up of the ore sorter and calibration against proprietary image processing software. To achieve this, images were taken of the samples by subjecting them to “static” tests to determine their response to the TOMRA X-Ray Transmission (XRT) system.

The X-ray sensor signal is a function of the sample atomic density and provides information on its composition. By combining two energy levels simultaneously, it is possible to differentiate particles by their relative atomic densities.

Assays were completed and provided by Bureau Veritas Adelaide.

For the purposes of the testwork, the sample was screened to 16-48mm and separated into a high-grade fines stream (not sorted) and two TOMRA Feed streams (Sample 1 – 316kg at 12.5g/t Au, Sample 2 – 264kg @ 13.2g/t Au). The TOMRA Feed was then sorted into concentrate (targeting galena) and waste streams, with the waste stream reprocessed again through the XRT targeting all sulphides. The upgrade factor, which includes the TOMRA concentrate stream as well as the high-grade bypass material, resulted in a gold upgrade of 41.6%, a decrease in sample mass of 33.7% , and a 2.6% loss in contained gold.

Ore sorting implications

The Company’s 100%-owned Lucky Strike processing facility is located 50km via road from the Gold Links Gold Mine. Lucky Strike was recommissioned in 2018 with a throughput capacity of 33,000tpa. The plant includes a primary circuit for the extraction of nuggety or free gold from the veins. A secondary flotation circuit allows for the production of a gold-silver-lead concentrate.

By implementing ore sorting technology after primary crushing, the tonnage going into the primary and secondary circuits may be materially decreased by ~33%. For Dateline, this translates into the ability to mine and transport up to 45,000tpa to Lucky Strike for processing through the 33,000tpa plant.

Subject to further analysis and modelling, there is the potential to increase future gold production by 40% compared to not installing ore sorting technology.

New testwork program

Following the success of the recent ore sorting program for Gold Links, the Company plans to expand the study with a new sample expected to be dispatched to a laboratory in Kentucky during Q3.

The new testwork program will investigate the potential of a different model ore sorter that incorporates the laser and XRT within the same machine.

Discussions have commenced with various suppliers for the purchase or lease of ore sorting equipment for Gold Links.

CORPORATE

Colosseum transaction update

During the quarter, the Company completed the first US$0.5 million payment as part of the consideration terms. The Company is progressing the establishment of US banking facilities that will allow the completion of the acquisition, expected to occur during Q3.
