Aclara Resources Inc. (“Aclara” or the “Company”) (TSX: ARA) is pleased to announce the results of a preliminary economic analysis (the “PEA”) on its regolith-hosted ion adsorption clay project located in the State of Goiás, Brazil, known as the Carina Module (the “Project”).
The technical report titled “Preliminary Economic Assessment – Carina Rare Earth Element Project – Nova Roma, Goiás, Brazil” (the “Report” or “Carina Module PEA”) and dated January 12, 2024 and was prepared in accordance with National Instrument 43-101- Standards of Disclosure for Mineral Projects (“NI 43-101”) by G21 Consultoria Mineral (“GE21”), a specialized, independent mineral consulting company located in Belo Horizonte, Brazil. The Report, which has an effective date of November 3, 2023, supports the disclosure made by Aclara in its December 12, 2023 press release announcing the maiden mineral resources estimate (MRE) for the Project (“December 2023 Press Release”). There are no material differences in the mineral resources or results of the preliminary economic assessment as described in the Report and the results disclosed in the December 2023 Press Release. The Report has been filed, and can be found under the Company’s profile, on SEDAR+ (www.sedarplus.ca) and on Aclara’s website (www.aclara-re.com).

Low initial capital costs of US$576 million with a payback period of 3.6 years
Average annual1 net revenue and EBITDA of US$474 million and US$340 million, respectively
Low average production cost of US$13.1 per tonne
Long-term rare earth price forecasts provided by Argus Media and Adamas Intelligence, underpinned by compelling supply/demand fundamentals

Significant production of magnetic REEs

Average annual1 production of 208 tonnes DyTb representing approximately 13.7% of China’s 2023 official production2
Average annual1 production of 1,190 tonnes NdPr contributing to a balanced mix of light and heavy REEs in the final product

High product quality

Concentration of REEs in the mixed carbonate of 91.9%3
Very high content of DyTb and NdPr at 4.7% and 26.4%, respectively
High purity product facilitates further separation and recoveries

Low environmental impact

Process designed to minimize environmental impact: it does not use explosives; there is no crushing nor milling; approximately 95% of the water used is recirculated; the main reagent is a common fertilizer; no liquid residue is produced, negating the need of a tailings dam
Minimal CO2 footprint is supported by a combination of low energy consumption and a high percentage of renewable energy within the Goiás power grid

Expedited path to early production

The pilot plant, currently in operation, de-risks metallurgical recoveries
The State of Goiás has fully approved another ionic clay REE producer (Serra Verde), thereby establishing a significant precedent that provides a positive permitting background for new projects in this State
Commissioning estimated to commence in 2029

Upside potential

Drilling campaign underway to increase mineral resources
Metallurgical optimizations have been identified

Researchers build AI-driven sarcasm detector

Artificial intelligence has made remarkable strides, from passing bar exams to reading bedtime stories with emotion. Yet, despite these feats, it still falls short of matching the intricate nuances of human communication—particularly, the art of sarcasm.
However, researchers in the Netherlands are determined to change that narrative. They have developed an AI-driven sarcasm detector that can discern when sarcasm is being used, a feat previously thought to be exclusive to human cognition.
Matt Coler, from the University of Groningen’s speech technology lab, expresses excitement about the project’s progress. He emphasizes the importance of understanding sarcasm, a pervasive aspect of human discourse, to facilitate seamless communication between humans and machines.
Recognizing sarcasm poses challenges due to its subtlety, especially in text-based interactions where cues like tone and facial expressions are absent. To overcome this, researchers trained their AI using a combination of text, audio, and emotional content from popular sitcoms like Friends and The Big Bang Theory.
The AI, trained on annotated data from these shows, demonstrated an impressive ability to detect sarcasm in unlabelled exchanges from the sitcoms, achieving an accuracy rate of nearly 75%. Further enhancements are underway, including incorporating visual cues like eyebrow movements and smirks, to improve accuracy even more.
Beyond enhancing interactions with AI assistants, this technology holds potential for detecting negative language and identifying instances of abuse or hate speech. However, as AI becomes more adept at understanding sarcasm, questions arise about its potential to wield sarcasm itself.
Coler muses about the implications of machines responding with sarcasm, raising concerns about clarity in communication. Nonetheless, advancements in AI-driven sarcasm detection offer promising prospects for improving human-machine interactions and bridging the gap between artificial and human intelligence.

AI, bias and experiments: how Women in News is tackling tech’s inbuilt stereotypes

Issues surrounding bias in AI are deeply rooted in the accuracy, trustworthiness, and quality of data, which, if overlooked, can significantly skew outcomes. Lyndsey Jones, an AI author and transformation coach, delves into these concerns, offering valuable insights for newsrooms on monitoring and reviewing data.
Madhumita Murgia, an AI journalist and the first artificial intelligence editor of the Financial Times, sheds light on how women, migrants, precarious workers, and minority groups are disproportionately affected by the technical limitations of Generative AI. Murgia emphasizes the lack of representation of these groups in the development process of AI technologies, highlighting the need for inclusive participation.
WAN-IFRA Women In News workshops on the Age of AI in the newsroom have brought bias effects to the forefront. Through the Digital ABCs training program, media professionals are equipped with skills to navigate the digital landscape and drive organizational change.
A newly launched module focuses on AI, with over 100 participants in eastern Europe taking part, now extended to journalists in parts of Africa, the Middle East, and Southeast Asia. Instances of bias surfaced during the training, such as generating offensive avatars and misinterpretation of accents in AI tools.
Google CEO Sundar Pichai’s acknowledgment of biased AI tools reflects ongoing concerns in the industry. Timnet Gebru’s dismissal from Google for highlighting biases further underscores the need for vigilance in addressing these issues.
Diverse teams in WIN’s Age of AI program are experimenting with various tools like fact-checking and enhancing staff skill sets in AI usage. Projects under consideration for further EU funding include a video lab for content amplification and an AI avatar for journalist safety.
Media companies must ensure diverse staff collaboration when testing AI tools. Quotas for women in AI research and cross-border partnerships may be necessary for smaller media groups to compete effectively.
Journalists can take steps to improve content quality by examining storytelling practices and ensuring diversity in sources and representation. Consistency of data collection across departments and assessing biases in data sets are crucial for ethical AI usage in journalism. Ultimately, AI tools should be used to enhance journalism’s quality and integrity, rather than generating clickbait or misinformation.
