MAJOR SHAREHOLDE RSRS
Dateline Resources Limited (ASX: DTR) ( Dateline or the Company ) is pleased to announce the Company’s REE and carbonatite experts, Dr Anthony N. Mariano, PhD. and Mr Anthony Mariano Jr, have reported their findings of the February 2022 field work to the Company.
The Mountain Pass REE mine is located ~10km south-east of the Colosseum mine. The Mountain Pass REE mine is the only operating REE mine in the USA. Messrs Mariano have been mapping, sampling and advising on REEs in the Mountain Pass area for over 50 years.

“The presence of lithologies associated with mantle derived systems such as the Mountain Pass Alkaline-Carbonatite system have not only been confirmed to exist in the Colosseum claim area, but additional previously unknown outcrop occurrences have been found through this field investigation. The occurrence of multiple outcrops of these lithologies at a distance of almost a mile apart within the Colosseum claims suggest the possibility of a large underlying alkaline carbonatite occurrence”

Site Visit Observations
ASX Release 27 April 2022
The geological team visited a number of prospects and outcrops within the Colosseum claims during the site visit. Several of these locations were based on historical observations, whilst others were visited based on radiometric data and earlier site visits.
The geological team observed and noted several different rock types associated with the outcrops, including fenites and trachytes (Figure 2). Both rock types are lithologically related to carbonatite complexes and the Company’s REE experts believe the rocks are genetically related to the geological events that created the nearby Mountain Pass carbonatite complex.

Sampling and Analysis
Four samples were collected and submitted for laboratory analysis (ICP/MS). Lab results showed the relative lanthanide distribution of the rare earth elements for three of the five samples analysed to be similar to rocks associated with carbonatite complexes (i.e. no negative europium (Eu) anomaly). Two other samples showed a negative Eu anomaly as would be expected in crustal derived granitic gneisses.

Petrographic and Cathodoluminescence Analysis
As well as the ICP/MS analysis, the samples were also subject to petrographic and cathodoluminescence analysis (CL). The CL was particularly revealing in that it showed the brilliant red luminescence in the feldspars from Fe[3+] activation typical of fenites.
Figures 4 and 4a show CL micrographs of sample COR-8 and AMP 0-12 collected from within the Colosseum claim boundary. Figure 4b is a CL micrograph of sample taken from the Mountain REE mine
All three samples show similar brilliant red luminescence in the feldspars that are typical of fenites.

Summary and Next Steps
The findings from this site visit are encouraging for the following reasons:
-
The presence of lithologies associated with mantle derived systems such as the Mountain Pass Alkaline-Carbonatite system have not only been confirmed to exist in the Colosseum claim area, but additional previously unknown outcrop occurrences have been found through this field investigation.
-
Several analytical techniques used in evaluation of the samples provide data confirming the nature of these rock types.
-
The occurrence of multiple outcrops of these lithologies at a distance of almost a mile apart within the Colosseum claims suggest the possibility of a large underlying alkaline carbonatite occurrence.
-
Future work to map the Colosseum claim area for the presence of these lithologies and investigate the possibility of structural controls related to their emplacement is warranted.
The Company intends to complete a detailed mapping program across all the claims in Q2 2022, before planning a drilling program.
This announcement has been authorised for release on ASX by the Company's Board of Directors.

Sample preparation and any exploration information in this announcement is based upon work reviewed by Mr Greg Hall who is a Chartered Professional of the Australasian Institute of Mining and Metallurgy (CP-IMM). Mr Hall has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to quality as a Competent Person as defined in the 2012 Edition of the "Australasian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves" (JORC Code). Mr Hall is a Non-Executive Director of Dateline Resources Limited and consents to the inclusion in the report of the matters based on this information in the form and context in which it appears.
About Dateline Resources Limited
Dateline Resources Limited (ASX: DTR) is an Australian publicly listed company focused on gold mining and exploration in North America. The Company owns 100% of the Gold Links and Green Mountain Projects in Colorado, USA and 100% of the Colosseum Gold Mine in California.
The Gold Links Gold Mine is a historic high-grade gold mining project where over 150,000 ounces of gold was mined from high-grade veins. Mineralisation can be traced on surface and underground for almost 6km from the Northern to the Southern sections of the project. The Company aims to delineate sufficient Mineral Resources to commence a small high-grade, low-cost operation by the end of 2021.
The Company owns the Lucky Strike gold mill, located 50km from the Gold Links mine, within the Green Mountain Project. It is proposed that ore from Gold Links would be transported to Lucky Strike for processing.
The Colosseum Gold Mine is located in the Walker Lane Trend in East San Bernardino County, California and produced approximately 344,000 ounces of gold (see ASX release 15 March 2021). Significant potential remains for extension to mineralization at depth.
